In my game "The Realm of Might and Mystery" One of my players: A kenku multiclassing level 2 illusion school wizard and level 2 Trickery Domain Cleric. For some reason, their Performance Stat keeps increasing and it's reached a 50 modifier when it's supposed to be 5, a while ago it was 45 but when I tried to see if it was a glitch by removing the proficiency and adding it on again it increased to 50. I've done a temporary fix by adding a -45 modifier in the settings tab. but I'd like a permanent fix if possible. Has this happened to anyone else and if so did you fix it? (If yes how?)
