using firefox latest version. up to date flash player. full screen mouse control and just about everything else turned off apart from the sound. always seems to happen to me when the map i am playing on gets full. very occasionally will happen when map not full. tried usual tips and find that the only way i can get out of the brown screen is to quit the battle. (problem then is somebody will jump in before i can get back into the battle again.) even if there are only a few seconds left it happens and when teh game restarts on that map brown screen still there. getting to the point that i may just give up and play something less buggy.

Well played the game with the update. joined in a battle on the loosing team n capture the flag. game took an age loading and when i first joined the blue team had 3 flags. by the time the game had loaded they had 4 by the time i had moved my tank forward a small amoun t the game was over. previously could at least get a few flags back. not bothered about getting crystals just wanted to go and shoot a few tanks and have a bit of fun. sorry but this update isn't and update but a downgrade.

happens to me usually when the number of people in a battle reaches a maximum. using firefox as the browser and disabled just about everything in the settings bar the sound. can hear the battle but just get a black screen with the updates of who has done what to whom. does occasionally happen with just one or two in the battle but normally for me it is when the battle is full. annoying yes. loss of crystals gained during battle never checked. way round losing crystals. pause game for three minutes at a time until battle finishes if more than 5 mins remaining. not an ideal solution to loss of crystals but it works for me.
