I was playing without any problems, but them it crashed and showed that error. I removed the mod and it seems to work, but if i put the mod again and try to load my world it crashes again with the same error. I have the glowstone glass on my base and that seems to be causing the error.

Much More Mod Compat works as of commit b0a5f25 (Release 2.1.0)
