Hi, I just came accross this bug.
I am playing 1.05 but started with 1.03. This may be a hint to the bug:
I had talked to Hiravias before but preferred to not add him to the group because I dindn't want him to be low level and sit at the stronghold.
I just unlocked Hiravias. I am almost sure he was like this from the start. I noticed it in his stats when equipping him with weapons and armor and stuff which was immediately after recruiting him. I assumed he was damaged, (although his health was maxed) so it was strange.
After going to Elmshore, travelling 12 hours, he was critically fatigued, and I rested. It didn't change his endurance.
Here are my saves after getting him, the autosave was prior to rest:

If any help, Ithe latest save before recruiting, so you can try. Hope it helps.
