Bell 407 engine issue

[Romeo_MSK]

I cannot make a thing run. When I start the mission in dark and cold heli the engine fail to start either way, manually or by pressing Ctrl+E. When I start ready to fly or in midair - engine shuts down and refuses to start again. But when I crash (afrer non-AR fall), the mission restarts and from that moment on no more problems until I land.

I start and fly this heli in 2020 without any magic.
Cabri G2 starts and flies normally.
