ISSUE DESCRIPTION

Description of the issue:

[PC Only] Did you remove all your community mods/add-ons? If yes, are you still experiencing the issue?

FREQUENCY OF ISSUE

How often does this occur for you (Example: Just once, every time on sim load, intermittently)?
Quite often during the longest overnight flights 12h - 13h long flight in 737 after skipping to shutdown. Good bye 15 million and 3 hours of real life. :anguished:
If any help - Altitude changed before the flight from 35000 to 25000. Sim-Rate 1 and 2 used during the flight at different times. Cancelled IFR after take off and resumed IFR 15-20 minutes before landing.

You could at least allow the game to count the time we spend in the air in real life, not only if we successfully land or complete mission. In 24 hours this is 2 bugged long flights. First - the game didn’t let me complete the mission because my landing didn’t trigger correctly, I landed and nothing. I tried to take off to force the update of the mission, and crashed because of another 737 bug. Now this error after a long 12h flight, another 3 hours wasted. That’s about 15 hours of my real life wasted and not counted towards the passive income. This is infuriating.

REPRODUCTION STEPS

Vol TNCA - KIAH

Just skipped to shutdown due lots of ATC issues and got the same error.

Same issue on a special VIP flight from Enfidha to Doha today. Problems started to happen after skipping to descent, being unable to respond to ATC prompts. I followed the flight plan and landed anyway. Still not able to contact ATC at hold short. Tried to skip to shutdown to avoid a taxiway violation but got Unexpected error code 309-400-00210 (see screenshot below).
If relevant, provide additional screenshots/video:

• Also experienced this with the new tornado mission (08/07/2025) upon skipping to finale

Same thing happened to me:

It happened for the first time yesterday (29/07/2025) when I tried to use fast travel at the end of a 1-hour mission (VIP transport with a B737) because the parking spot was really far away (and I had other things to do). When I used fast travel, the mission stopped and I got the following message:

Unexpected error

An unexpected error has occurred: you can no longer continue this mission.
You will be redirected to your last position.

Error code: 309-400-00210

At first, I thought it was just a one-time issue with that mission since it was a special one I had already completed before.
However, the same thing happened today with another mission (tornado with the AeroElvira Optica). The first time I did it, I used fast travel for the return leg (after flying around the tornado), and the same message appeared. To be sure, I launched the mission again and was able to use fast travel successfully up until the return to the airport after the tornado, so at the same moment as the first time.

It’s quite frustrating, so I hope this issue can be resolved quickly!

Thank you!

Note: I am playing on PC, Version 1.4.20.0 of MFS 2024.

I don’t think that ‘Unexpected Error’ should trigger loss of reputation or income like it does. I have had this a couple of times, never at a convenient time to create a screenshot, and the resulting loss of reputation is just a nasty little kicker…
