2.2.1

Fixed: using the "undo" button on a damage/healing card threw off the stats. If you ever clicked that little revert arrow on a chat card, the health change was undone but the stats kept the wrong numbers. Small note: your single biggest hit/heal record and kill count won't be adjusted if you undo the exact thing that set them, that edge case is still on the to-do list.
Reported by a user, thejoester on reddit, confirmed fixed live. Thanks for the catch!
