Just a quick note.

1. Guards that come to help start fighting each other.

While they fight foes, I guess they've hit each other, I'm not sure, and thus started fighting each other.

Didn't try to reproduce.

2. Foes will only target guards.

As guards were stuck fighting each other near the entry to the cave, I met a foe that talked, answered some questions, and then attacked "me": he ran past me, and to the guards to fight them, running all the way to the other side of the cave to reach them.

I had noticed this with the first foes that attacked us in that same cave, but it was less shocking because they were in sight of the guards too.

Just two small things that break immersion in this fabulous questline.

Not sure if this is simply Morrowind's behaviour, if it can be avoided at all.
