SAS BAT Ki-15
 

I've noticed an issue with this plane, if it goes above 3200m and autopilot or level autopilot is enabled after a bit of flying the plane dives nose down into the terrain. Sometimes it happens when turning on sharp waypoint turns at 3000m.

Anyone else getting this issue? I'm using farang's darwin map

this test mission should show it: https://gofile.io/d/LTFKeQ
