I sat down at typing derby for the 2nd time with no problem so far as when the countdown was at 4 seconds remaining to start the game I opened up chat with “Y” to type something then closed it, the game then started and a giant green overlay appeared so I typed it and it allowed me to type a few letters with noises but then I couldn’t input anything any longer and was stuck until the round finished.
When it ended the scoreboard got stuck on my screen, had to disconnect to get rid of it.
P.S. the other guy could still type and finish the race
