Hello, I just bought 2 name change tickets one on my old account and one on the one i made and currently play, but after changing my old account character and trying to put it on my new one, it says "Invalid character name". I would like to know if i can take the nick back, would be great.

Hello,

Please, try after the maintenance. 

The old names go to cache and normally cannot be used again. However, we clear this cache at the maintenances.
