I am experiencing some very odd lockups or console issues during or after playing Minecraft BTU.

1) Sometimes the Xbox menus won't activate from within the game and I get the generic error message I've seen for other problems telling me to reboot if the Close button doesn't work. (I see this error whenever I try to convert a world that is too big.) I have to hard reboot to restore usability. Sometimes I can keep playing but can't exit to the home page.
2) The game will crash and require a hard reset to restore. Once it rebooted on its own.
3) The game will exit fine, but then the Xbox will not launch anything else and I have to hard reset to fix.
4) The Xbox in general is unstable after playing Minecraft BTU. Everything is sluggish and it's safer to hard reset before playing anything.

Something is happening here. Memory issues, not properly closing out, I don't know. But it is a pain having to reboot each time I want to switch to another game, or in those cases where Minecraft has crashed.
