Thank you for playing ! Yes, it was a very weird bug that did not appear during my (somewhat limited) play testing. Have only encountered it once after the submission deadline and I believe you were the first one to mention it also.
I am also not sure how it happened but I am guessing that I have doubled the addition of the 'claw (tooth)' in the item pool, which in turn caused the game to not detect the correct amount of items in the board.
Although I am happy that this seems to be the only bug report (so far :P), thank you again for the kind words !
