I do have live traffic activated. Thanks.
Sounds like the issue could be live traffic related. I wonder if it’s related to people having liveries installed (like I do), that have been changed by Asobo, and MSFS is trying to load liveries and not finding the new texture sheets Asobo created for several planes (without telling anyone), and finding files in Layout.json it no longer needs, and causing loading issues with live traffic? Total speculation.
So many moving parts in this sim…and very few are exposed
I am not flying with live traffic on but i use LNM. So i turned that options off which they were talking about in the topic and downloaded new 1.0.23 version and didn’t have CTD.
You change TWO things at the same time, making it difficult to tell which stopped any possible CTDs ..
That’s true 
That was only one flight. I’m gonna test it in the next few days
The Beta testing by a MSFS user is never ending !!
I’m using the .23 release and notice that I can reproduce a complete freeze of the sim for what seems like 1+ minute (I’ve not timed it) and it seems to happen when adding VORs when inputting a flight plan. For example if I add the Colts Neck VOR COL to a flight plan, after entering the “C” it seems to freeze (assuming it happens to anything stating with C of course). I actually assumed the game was frozen and would require a reboot, but after leaving it frozen realized it actually comes back and runs fine after the freeze.
Not sure if this is a well known issue or not, but to be clear I’m using the Navigraph navdata beta (updated to latest version as of a day or two ago) so perhaps that’s the issue. Thought I’d raise it just in case.
I just saw this function on the CJ4, that may be used for the direct to with selected track on the GNS530 mod :
Added VFR runway approaches - in DEP/ARR you can now choose a VFR runway for landing and specify a runway extension waypoint to be added to the flight plan as far as 25nm from the runway. This allows you to ‘roll your own’ LNAV/VNAV approach to any runway at any airport. Great for small/private fields!
This is something I saw for a long time now. Not related to the MOD nor navigraph.
When adding a waypoint manually, the search process is managed at the kernel level so the issue is probably here inside the kernel.
Thanks
Will check that but it should be better if the Sim’s kernel provides the OBS function. Still waiting for that.
Happens to me as well, but also with the default GNS.
There are some inputs where it always happens, but sometimes it also happens on inputs where it usually doesn’t.
Good thing is it seems to happen only once per flight, so on every flight with a GNS aircraft I just trigger it at the beginning so I’m safe for the rest of the flight.
Thanks for the response, I didn’t realize this was a known issue in the sim itself. Guess I just have to factor a few minute pause during start up in each flight! Hopefully they’ll fix it at some point.
Version 1.0.23 seems to cured my CTD problems, thank’s 
Seems that there is no public way to add a user waypoint to the sim for now from javascript code.
They only provide a function for adding a valid ICAO waypoint.
There are some FS9 commands for doing that but they don’t seem to work
If you save your flight plan with LNM, you can reload it in the game from the global map load/save button. Your user waypoints will be here because the loading process is provided by the kernel itself. They will disappear if you try to insert a waypoint from the GPS because I cannot rebuild these user waypoints.
The problem at my level is that the kernel doesn’t expose any function to add a waypoint just from ident and coordinates, or it’s hidden. Maybe in a future update (or SDK doc update)… in year 20 201 as you said. 
WorkingTitle have figured this out; latest progress showed user waypoints in the CJ4 FMC.
So a MSFS Map generated FP can have User waypoints.- and can be saved.
(1) Could the GPS Mod created user waypoints using the same format as the MSFS map generated one.
(2) Could a LNM FP with LNM user waypoints be “processed” to reformat those LNM user waypoints to MSFS compatible Waypoints.

Not tried out v23 yet, but very excited to see saved Settings
Can’t just have the G1000 guys having that additional function 
Where do they get saved, and are they accessible & editable outside of MSFS ?
Great — there are certainly a lot of very talented programmers working on these Mods, and with a shared, combined effort, everyone is benefiting – which is a wonderful thing.
Very different to the Commercial Dev guys, who seem to guard any new ideas and techniques , like gold, and will not share their new “toys”.
Which is why, I would much rather donate to the MOD guys, than pay the Commercial Guys for their “so-so” efforts.
I checked their code. They have rebuilt a complete flight plan manager that is able to insert user waypoints but I’m not sure that these user waypoints are really transmitted to the sim. The code seems to say “no”. I asked them.
I spent hours to check for solutions. No way for now. Loading is made on the kernel and they do not expose any command to load a (file) flight plan nor to add a user waypoint.
I appreciate all that hard work and time spent.
I was also mistaken, it seems one cannot even add Custom waypoints manually when in the MAP.. (I thought one could and that I had done it before .. but maybe not)
So the only “custom waypoints” seem to be the ones the SIM generates and adds as it see’s fit …
Maybe that will change in 2021 or 2022 … but since it’s not possible at the moment, no reason to obsess over it’s lacking .. many other things are possible & doable.
