PPS: with VPN have same bug, so i think that a “mission bug”

I tried to log in with your account and I got “duplicate login”. So I assume you got this to work in the end?

PPPS: i try to edit, but didn’t find button for it, so one more reply:

Today, in the morning, when you try to connect and watch, i had a auto update (10 minutes before) game in steam. After that update mission work correctly.
Idk why it bug again - it’s hard to me =)

What i to do more: i update video driver - but it doesn’t helpefull :frowning:
Just in case:
GeForce RTX 3060. Version 32.0.15.9571 27.02.2026
win10 build 4170
Redistributable and .NET Runtime installed

So it was you :smiley: I thought that was a bug and recconect again.
It might sound stupid, but I went back into that mission and got a black screen with a connection error again.
Now i leave game and stop check ( now check only here) - you can watch what wrong there…

I can log in normally in your account and resume flying your mission, so if you are still having problems, it’s most likely a network issue. Temporarily disable your NAT (if you’re using one).

If you get a connection error again, write down what it says exactly and post it here.
