As far as I can tell, then rendering EE3 minium stone causes my game to crash. It worked welll so far, but after adding MagicBees mod, then every time I wield minium stone in my hand, then game crashes.

Crash log is here: http://pastebin.com/u22atnpt

This is my first bug report ever in any mod, so be gentle if some information is missing...

Update to Forge build 727 or higher

Thank you! Sorry for bothering. I didn't know it was so simple problem...
If I may ask, where in the crash log it tell that I should update forge or do I recognize it? I am kinda also studying Java, but my knowledge is yet very basic...
I would appreciate if someone tells me that :)

Nowhere. You can see it on forge changelog, MinecraftForge/MinecraftForge#601 and MinecraftForge/MinecraftForge@9034862

Thank you! At least now I know where to look first if I have any problem with forge mods :)
