It's got a couple of annoying behaviours still (the win message pops up every time you switch between random and word of the day, and if you playing in random mode and refresh the browser it will clear your current attempt). But can you have a go in Chrome (not Chrome, Edge sorry - the one where you should have a history) and see if you still have your game history - complete the word (succeed for fail as you wish - fail is obviously quicker) and see if the stats modal when it pops up still records your previous games.
