On Fire Temple Third Floor, just after leaving the safe room, the game crashes with this error. This also happened on the next level, just after getting the hammer.

Reinstalling doesn't fix it, and it occurs on local hosting. (Might happen on other types of servers too, though.)

I don't know if you're still working on this mod dude, but I can provide more information/screenshots, or do more testing if you'd like. Just bringing it to your attention in case you are still doing bug fixes.
