Firstly, many people are wondering where their levels went. A new server opened today (12) and you're logged into that by default. If you're like me, you were on server 11, so change it back and your levels are there.
Next, I can't seem to get past the loading screen when I try to fight something. The loading screen completes then the screen goes completely white. The music continues to play but I can't see or do anything. I have not been able to fix this yet. I have shut off ad block and have run CCleaner, nothing has worked. It wasn't doing this prior to the addition of the new server. I tried to start a battle on the new server and it doesn't work there either. Not sure what happened but this game is currently unplayable for me. Hope it's fixed soon.
