I just notice an AI player just cast a familiar and the familiar's hitpoints say 12 / 10. I was able to see this duplicated by waiting for the AI to cast familiar.
Note: If you go to the details screen of the familiar everything reads correctly.
Note: End turn fixes the hitpoints back to 10 / 10.
Note: I did save the game, but a reload gives the correct hitpoint display.
If there is anything you would like for this let me know.
