I was playing monster with a controller for the first time, then after the game, I unplugged it. It is only in the post game menu that this happened.
Remember the elusive cursor bug? This removed the cursor entirely. I could not click on any buttons. This left me to wait for the timer, then all was good.
This bug persisted into the next game, in the same place. ( i did not plug in the controller during that time).
I also tried to plug it back in, and there was no change to the interface.
I restarted the client to see if it was repeatable, and it was.
This is a minor, edge case bug. Thought i should report it anyway.
