Last night I played a 3v3 Cataract match as TB. I typically play a hybrid build, but a little into the game I realized that my TB was not auto-attacking in Ice Mode. It would simply chase the enemy Demigod, but once it got into range, it would do nothing, just stand there. No amount of clicking or using skills or form dancing did any good. Changing targets did nothing as well. Ice TB refused to AA anything. Ended up having to stick to Fire for the rest of the game -- at least it still did some sort of AA.

This is the first time I've had this issue since I've played this game. After the match, I started up a single player skirmish and my TB was back to normal.

I don't know what could have caused the bug, and it might be rare, but still rather annoying when it does happen.
