[Attack of B team Crash on startup]

I don't understand how a faulty mod could cause it to all of a sudden stop working for everyone.

I feel I should note that this MIGHT cause some issues if you were in a morph when you logged out on a singleplayer world. Can't confirm because I wasn't morphed in my world.

I was morphed in a single player world and I didn't have any issues after removing the morphbeta file. Only issue I could maybe see is if you were in the air flying and then remove morph and you fall to your death.

Crashing for me after the Mojang screen as well. Also using a Mac. I tried reverting to an older build (1.0.3) and it still didn't work.
