Hey guys, in one of the levels I made, the blowtorches aren't burning the lemmings, no matter how close i get, I'm using CustLemm to play my levels btw, if that helps any.
Check the object's z-order. In order for the object's effect to take place its z-order must be 15 or lower. Objects with z-order above 15 are effectively "fake objects" that won't affect the lemmings.
