Example, set Brigitte ability 2 charge to 1.5. The charges are then set to 2 (due to rounding) and then continue to charge past 3 (the normal max) up to 4.
This actually sounds pretty cool, I hope they let us charge things over their default max value (but still fix this bug)
I know, it sounds like a bug that would be fun to abuse. If only it wasn’t a byproduct of the action being weak and unable to handle the number 1.5.
