So I had this mage Ilia as my follower, rescued from her evil mother, well anyway, we went to a certain tomb where a guy was waiting outside and wanted me to help him, so off we went, all 3. Was fine for a while, but almost every time they ended up fighting each other. I suppose because Ilia is shooting ice bolts all around, and the guy got hit and started attacking her... pandemonium I had to leave Ilia waiting in a hall while I went in with that guy in the end and come pick her up after I was done. Kind of a bummer this happens, anyone else ran into the same kind of situation?

Delphine and the priest from Lady Azura's shrine kept beating eachother on the way to Kynesgrove for some reason.

Yes, I've had this happen at least once with Marcurio. I had to leave him waiting for me at the mouth of a cave so I could get through a quest. He kept getting into it with the guy we were following/supposed to be helping. We had a fight to get through in the cave to get to the boss beyond and Marcurio and the quest guy would end up fighting each other after that fight..every time. I tried it a two or three times before I finally gave up on taking Marcurio with me.

Sounds like gamesas decided not to implement code a modder helpfully created for Oblivion that prevents followers from attacking one another. Another thing for a modder to fix, I guess, when the CK comes out sometime in January.

Be sure to ask for this in the mod forum.

Somewhat unrelated, but as I was leveling pick-pocketing in Riften I got caught stealing from the Blacksmith. He pulled out a dagger and attacked me, a guard came up and I bribed my way out of it. Meanwhile all the towns-folk in the area killed the blacksmith. His apprentice came up and took his place pretty quick after that, but I still kinda felt bad about it.
