Worlds being completely ruined nonstop.

edit:
nevermind.
dont post.

idk whats going on, but it doesn't relate to Bukkit.

For some reason, half the time logging into a server crashes my MC client.
:|

 

"Whenever I exit the .bat without typing stop to shut it down, the world messes up." Red Alert...don't do that. It shouldn't screw things up, but it might.

 

Okay. At this point I have no clue if that's what's even causing this error or not.

I had one world working fine. I logged in and all was well. I log out and try to get back in. Boom. Error returns.
I go to the backup that was working fine.
Error.

It's happening half the time.

edit:
alright. it's happening with a brand new world too even without plugins loaded..

 

Pressing 5 keys can save the world... lol
