Bug reports.

Recently, I've encountered a rather unpleasant issue a couple of times. The game starts loading messages (sometimes I can't even understand why, as I didn't initiate it myself). And there's no way to exit. Nothing works. Neither Enter, Tab, nor Escape helps. I can't save the game or do anything at all. It's not a very pleasant situation; in the game, both times, I couldn't figure out anything to do except abruptly close it. Then I have to restart the battle.gm2 process, which (especially in a tournament) doesn't look very good.
Has anyone else encountered this and know a solution?
