When I was Playing this mod, my mouse started glitching and I had to restart, I was making my daughter fish, and when I returned it showed my inventory and a black screen, then crash. I tried it again and again, and again. Restarted my computer, etc. Nothing.
My crash report is this:

Unfortunately, MCA for 1.6.4 is no longer supported. To restore your world, you would need to load it up in a world editor like MCEdit and delete your daughter.
