Just happened to me to, typod a letter and got the error message. As someone who runs their own online game, a 1 hour waiting time is extremely far-fetched. Mine is a 5 minute wait at first, after which you only have 1 attempt to put it in correctly otherwise the timer doubles. 5 minutes, to 10 minutes, to 20, and so on. 1 hour though... Jesus christ lmao, intelligent.
