Thanks for the info on the 32/64 bit. Knowing MC, I'm sure it probably is a memory leak [] . I actually just reset the pack, and it doesn't seem so bad. I'm sure lady luck isn't on my side, and the problem will still arise, but thanks a lot for the post, buddy.
I might try removing some mods and seeing if that helps, if not, I guess its back to MS Paint and solitaire. hahaha.
Edit: did a few things, removed the redpower mod, and my memory seems a bit better - still getting crashes, just not as often. If anyone knows how to remove Forge Microblocks, please post on this topic: '?do=embed' frameborder='0' data-embedContent>>
(Sorry for 2 different topics, I figured they were, well different topics, so yeah..)
