I mentioned on the general acf thread that the generic fire death causes extreme amounts of lag when dealing with high prop contraptions.
I still think engines / ammo / fueltanks should set on fire when they die but it really does not make sense for say a piece of tread or armor to spontaneously combust.
So if you see it fit would you be willing to disable the generic fire death on non flammable props?
Edit: XCF has it like this now as of a few minutes ago so its not an immediate issue.
