MSFS2020 is a great simulation, but it is buggy as hell. I really have enough of developers spending hours to improve the smoothness of clouds, when the app crashes and shows unwanted behaviour so often. Most of the time not reproducable, so no way you can log a decent bug report.
Examples: save a flight mid-air, come back a day later, load it, everything is messed up, flight plan is broken, instruments show wrong data.
Or: deleting a waypoint shortly before landing (after 5 hour flight) crashed the whole program. 5 hours for nothing.
Or: plane suddenly off-flight plan for no apprent reason, in the middle of cruise.
I could go on and on.
There seems to be no quality control in Asobo. I am not buying MSFS2024 until I am convinced they have fixed their quality issues.
Not disagreeing with you here. It has been an issue from day one.
Thing is, for a lot of people, including me, there is no other civ. sim to match it. Itās far from perfect but āwarts and allā the competition (for me anyway) is too far behind to be considered a viable alternative.
If you are waiting for these kind of issues to be fixed then I think you will be waiting a very long time.
MSFS 24 will have similar issues. I think it will be a better and more immersive sim/game though than FS 20 which is why I will most likely buy it although not from day one.
FWIW I think the new sim is going to have a massive uptake unlike XP 12 when that first launched. You only have to look at the multitude of simmers crying out for new scraps of info to get an idea of the interest in it.
The good thing though is that staying on FS 20 is still an option atm and nobody is being forced to update 
It is a bit buggy no doubt, i also would like to see more time invested in fixing bugsā¦ but priority seems to be to put out new content above all else.
a few comments
yes, the save feature is broken, it has been from day one, and no one seems to care, i am hoping 2024 will deliver improvements on this
yes interacting with the FMC after a long flight, and sometimes even a short one, crashes the sim in one way or another, sometimes the cockpit freezes and sometimes its a CTD
this i havenāt seenā¦ what i did see is one fp in the vfr map, and different one loaded on the fmc, that may be the case
i will
with all its bugs, its still the best one, you cant beat the scenery
and another thingā¦
i think (dont know) but i thinkā¦ that 2020 was conceived mainly as a vfr sim for light aircraft.
The long distance tube flights were not a priority. They BECAME a priority for a lot users thoughā¦ (me included) but the original architecture doesnt acommodate it very well
2024 will include one the ācareer modesā as an airline pilot, soā¦ with any luckā¦ long distance tube flying maybe considered right from the get go and given the priority it deserves, and maybe de devs this time make sure you can finish a long haul flight without some sort of failure along the way.
MS/Asobo have the metrics to see what percentage of users actually do hard-core tube-flying where saving a flight mid-air, 5+ hours stability needs and extensive FMC use are common and important.
I suspect the majority of users are either very casual fliers, GA pilots or bush pilots where those issues/bugs are less of an issue, making them less of a priority in the overall scheme of needed improvements.
For a simulator that I only paid 120 NZD for (thatās basically
the price of twenty cappuccinos) this is an amazing product. Also add on to this free updates over four years, which when added up do improve the sim. With all the variables of live data, and different hardware combinations it must be a
nightmare to collate all this information, into a smooth seamless experience for
everyone. On top of that you also have to deal with the variables of the
internets capacity to deliver it to you in a timely fashion.
Bang for buck, this product is the best I have ever purchased, I am nearly
70 years old and have played many FLT Sims since 1988. As for MSFS 2024
I am looking forward to this (I expect bugs, but because I am guessing I will
only be paying about the same price as 2020, I can deal with it)
I congratulate MS/Asobo for what they have achieved and what
they plan.
We are all playing a part in making the sim bigger and better. It is a learning
process and takes time
I recently looked through a few of my previous posts on the bugs and poor ādesign featuresā Iāve noticed since launch. It is very sad to see that the large majority of these remain unresolved. And nothing from Asobo has suggested a significant number of them will be fixed in FS2024.
The new missions in FS2024 look very good from outside the aircraft (which is what is presented in the trailers), but I am only interested in the perspective in the cockpit, and this is decidedly lacking. For example, I suspect very little of the crop-spraying effects will be visible to the pilot, rather than a spectator.
So tbh I canāt get excited about fs2024, which is a pity. I have bought most previous versions of MS flight sims on day one, but not this time, though I will look at pilot-view videos of proper flights when available online in the hope that Iām wrong.
Itās first time I hear about the game crashing because you do something in FMC. I fly airliners most of the time and make changes in FMC in various stages of the flight. The game never crashed because of this. MSFS rarely crashes at all, maybe once a month and I play it daily.
This is not a bug.
This feature was never provided.
MSFS 2020 is by far the CHEAPEST program I have ever purchased, when you consider the cost in TBytes/Dollar, and all TBytes of FREE updates.
- It also probably has the LEAST BUGS / Tbyte of any games out there !!
You must have never played Frontier: First Encounters. 
The problem still exists within 100 years, and the key issue is caused by network transmission.
I was a dev manager for a sw company. I cannot imagine myself to publish a sw with so many bugs, imperfections and essential features not implemented. āEasyā things go for years without corrections, new buggy āfeaturesā are introduced and I can not undesrstand what (if any) debugging goes on at that MS team. Users start to get used to work around, third party addons but no basic improvement is happening to the base product.
Some bugs are far too ridiculous are arenāt even reported. We just work around.
----Features that we took for granted on previous versions are now gone. What will be gone in MSFS 2024?----
I Will wait and seeā¦
This has happened to me before, it is well known with PMDG.
Iām afraid that means youāre not buying MSFS2024 
The truth of this cannot be overestimated.
You will. You know you will. We all will. 
Yes that is maybe exactely what it means. But more than that the extreme negativity it is a attempt to convice others not to buy the software. Fortunately the opinion is there own and dose not reflect the millions of users who have a high opinion oF MSFS.
To be sure there ARE lots of bugs in the sim. It seems if you sneeze while itās booting something bad will happen.
But as Kayembee370 said, itās incredible if not just for the few times it DOES run well.
The problem for a lot of us is we just donāt have the time or patience to spend tweaking & troubleshooting & reading/searching for answers about it online. I have maybe an hour or two each week to use it and itās incredibly depressing when what worked yesterday for some reason doesnāt work today. Especially when just the boot time alone is over 5min for me
Oddly, MS Excel, Word, Access, and Win 11 work consistently 99.9% of the time, but MSFS2020ā¦ā¦maybe 30-40%.
The biggest issue with this sim is that it requires a computer to run it.
I donāt experience crashes on my system. Never have (save a couple that I could trace the cause of pretty easily.) Hence, itās a simple bit of logic to know that constant CTDās are not caused by the sim itself.
Buggy things (like the FMC issues OP talked about) are things that need to be addressed, for sure. I personally had my first experience with āblack screensā yesterday. I loaded a flight starting in the air in my Bonanza, and the G1000 screens were black. I exited and restarted the flight, and all was well. Thatās a bug. Was it annoying? Sure. But itās a computer.
I got into the air again, looked around, and thought how wonderful the world around me looked as I soared through it, boats in the harbor, other planes in the sky around me, and the sweet sound of the engine reverberating through my speakers.
These are good times, and I firmly believe this sim will only get more amazing in November.
You cannot say this unless you have used the sim in all locations, in all the aircraft, with all the settings in the options, using all the features of each aircraft (MCDU, Autopilot, VNav etc) in each location, in VR/2D, in Windows 10/11, using AMD/Intel/NVidia etc, etc, etcā¦ I know in writing software as part of my job that even years later, someone would use the programme in a particular way and cause a problem which needed fixing, and Iām sure even decades later that there are still many bugs in my programme which have not yet surfaced. And this was in a relatively uniform environment.
Underlining this, many sim updates which Asobo provide have a line in the release notes:
Just saying āit works on my system, therefore itās your faultā is extremely disrespectful.
