I was walking with my Frost Giant Bodyguard over nobbie river, killing crocodiles to level him up, when he sudelly disapeared. I walked few meters hoping he would teleport, but there was no sign of him. So I tried to track him using the thralls menu and when I set to locate him, I got the message that he died while following me. The Event log didn’t show anything.
I don’t know if he died because I tried to track him. He was full HP, and level 6. I can’t believe crocodiles or hyenas could be able to kill him. Is it a known bug?
