Solved Thermals(Air cooled engine)

Hey, working again on the B25 for the 7.0.x version of the game. I have one snatch, the new air cooled engine logic broke the thermals of the aircraft. The game engine says, libbeamng.lua.V.engine.intThermals|Wrong number of radiator nodes found. Should be at least 2, is: 0

So I know the problem, but adding radiators to an air cooled engine??? It worked the whole 6.x.x versions. Devs please clearify

 

Found the bug

 

What was it?

 

I must have changed some parts of the code and it broke the whole game, after reinstalling it worked again.
