ToME: the Tales of Maj'Eyal

While playing my Skeleton Writhing One with my cute Worm That Walks, I reached level 39 and entered the Greater Mummy dungeon. During the fight I had to run away, and after reaching the Fortress I noticed that I had two Worm That Walks. Both are stuck at exactly 66 HP, their buffs and debuffs no longer update when I take turns, and they cannot use abilities or receive orders. They visually follow me, but they don’t act, don’t move on their own and the only thing I can do is inspect them. Blindside still works to rush enemies, but the worms themselves do nothing. Leaving and reloading the game did not fix the issue, and the problem persists. The bug most likely occurred during the Greater Mummy fight.

Update: It was solved by leveling up.
