Prohibited name or character length not met, 3 chars min 20 chars max, numbers and letters only allowed. I want to use my nickname in Battle Arena: clubber. The last arena I was: clubberREBORN, the other one I was clubber2012. Now it doesn't allowed me at all to choose clubber. What is going on? P.S. Sorry for title typo.
I will get DEV'S Attention in a few hours when they get in, in the meantime send a message to support on it. It could just be a glitch or maybe someone is already using it, I have run into that message ,myself, so I just pick something else.
