It happens right after i load game

This sounds like incompatibility with other mod, OR maybe you were upgrading from an ancient version of Helicopters?

I was moving to inland radar post with helipad by using autopilot, thi n thinked about disabling realitsic aircrafts becuse it makes helicopter on some staight moments turn left/right (vhiecle snap was off) so i gone do mods and off it, then it tryed load game again but no sucksess, after eenablign mod it still boken

^ Curent enabled mods

Okay save wich was made 1 hour before this is ok

Jez 600 hrs game is almost fucked (i use time control so real time is less, a litthe more than 60)

Okay game crashes no matter of mods, but if you leave and load save wich had copter on autopilot and you're in it

Do you linked copter pathfind to ticks ? I assume it get screwed on first tick wich is 0

So... do you gonna fix it ? It realy not cool that if game saves when heli airbone you can easly corrupt you save file

It's on my TODO list. So, soon(TM)
