Minecraft crashes when I attempt to load any survival singleplayer (SSP) world.
Minecraft works normally on survival multiplayer (SMP).
Yes, I use mods, even if these reports say I don't. It still crashes without the mods I use, which are these: (all of them latest version) ModLoader, Optifine, Autoswitcher, TooManyItems, and thebombzen's API mod.
How do you reproduce this problem?
1. Open Minecraft
2. Choose any SSP world.
3. Attempt to open the world so you can play it.
4. Get an error/crash report screen.
Here's the last 3 crash reports I got. Yes, this is happening over and over and over....
