You're right, I missed that. Now provide useful details. For example, how do you know it's freezing right when the autosave occurs? Is this in a single world, or does it happen in every world? What game mode? What is in Modloader.txt?
I found the problem, but anyway
1)Because I tested these crashes quite thoroughly, where I could even induce them quite reliably.
2)Every world, that one was my bad I probably should've stated that.
3)Every mode, same as above.
I was methodically going through POSSIBLE problems (which was how I determined it only happened if the redpower core package was in the mods folder) when I decided to try something on a hunch. I redownloaded everything. Apparently something happened to the forge files when I downloaded them or later, because they're the same version, but it stopped crashing after I replaced it. Thanks for trying to help though, I do appreciate it.
I've worked tech support, so I know how annoying helping people with these things can be sometimes. I was literally trying everything instead of asking for help.
