Currently I'm conducting offline tests on all level bombers. For that I do use the AHTA08 and take off from 30K base.
So far, the B-26 is the only plane I found triggering the following error: After a few moments on the runway, the complete world disappears (including plane) all i see is the blue sky. No sound, no movement, I can't look into any direction. I'm just able to get back to tower by .ef
Funny thing is: After that I tried to take off in different planes from different bases, but suddenly got the same error. Even changing offline map didn't help, I had to restart AH.
I then checked if it's because of that very airfield and lifted the B-26 from a lower base and started to climb with vertical wind assistance. Same here: Once I broke 30k, the world disappeared and I had to restart AH to fly any plane.
This weird bug had only been triggered by taking a B-26 to 30k on any map.
