Crash when mining a triple slab. It tries to render a single block and gets confused. Needs a 1.5 height block for mining triple slabs.
It renders purple and black squares right before the crash.

Hi there! Apologies for the extremely long delay in response, I've had a hectic year at university and have only just had chance to look at the issues with the mod. I believe I have just fixed this so this should be fixed in the next version
