Close your game , then try to open the game . reconnect . If that still dont work , restart your computer and start the game again

Have you tried to open the option on ur client . Chose Repair client ? i got this bug before and i just need to restart the program and im fine @@

AFAIK that happens when you reconnect after a crash but that's a rare case and not 100% reproducible - we might have a possible fix tho!
