Btw, found a workaround - I renamed the interceptors, changing them from default to suggested new names, and now it works. So for mod devs - it seems the issue is connected somehow with the properties of interceptors...
When I engage a ufo the game crashes to desktop. I tried reloading from the savegame before intercept, however the same ufo appears and crash persists regardless of which interceptor or attack mode I choose. See attachment with log and savegame.
