For some reason, my client decided to stop responding to the mouse/keyboard and even controller. The game itself is working fine and even Alt-F4 works, but I cannot move or do anything in the client, i’m only able to quit.
I already tried to restart, remove LambdaMenu and delete cache.xml. Anyone else got this problem?
