I'm currently in vanilla1 [en] and most of the AFK mice don't seem to actually die from being AFK. Because of this, we need to wait until the end of the level countdown every round. (Unless if the shaman kills the AFK mice).
What's going on? Is this a hack?

Is it all AFK mice?

Well almost ALL of them. Some didn't die others did died.

Must be something with your browser or your com is lagging and it just froze?
