This happened when I tried to fix another bug :) Anyway, I updated the main server so it shouldn't happen too often anymore, but the problem is really in client, so until version 0.13, this bug won't be completely fixed. I uploaded fixed 0.12 client here: http://users.sentvid.org/~tomaz/fix/TASClient.zipSometimes when you try to join a game, you get a small window titled " Loading...", the client hangs and starts pegging the CPU... Only way out is to kill the process.
(This one doesn't have this issue anymore)
