here's a link to the bug you'll see it after the second spawn while turning on the right engine (doesn't spin up even with ground air supply)

I tried the same, that's why I uploaded it into my google drive :P
the file is downloadable but I made it a bit more easier now

it was happening at ~10:46:40 TO ~10:47:50 (Ingame Time)
I was locking the tanker and the range + the search angle was getting reset and I was also able to raise the value up to 252 degree
