0.C-9527-g2a74ce9 Acetelyne torch not working, hisss noise coming from above?

wierdly, when i use a acetylene torch on a metal door 1 Z level lower than the standard height, it appears to be working on the original level- i hear the hisses, but they come from above? any help?

edit: i think pressing a arrow key in the direction of the metal door while doing the aceteyline torch thing fixes it, either that or disabling the z level thing in the worldoptions file.

Looks like the acetylene torch is all wrong, it uses 0 coord for z-level.
Thanks for reporting
