At the moment stuff like this can happen:
You’re chatting, suddenly the key press pops up, you press the wrong key because of that.
or
You press the right key but press a wrong key right after having pressed the right key, so it still kicks you out but rewards you with the 150 units from pressing the right key, lol.
Edit:
Another thing that happened just now… I got thrown out of the casino even though there was no key press on the screen.
It just told me that I pressed the wrong key and boom… Apparently that’s a thing too…
