Strange battle results

[Falkor]

Hi!

I'm reading this great forum for 2 years already and playing dom2 and 3, but never posted anything. So, my first post here.
That was the intro. Now, to the point. I observed two strange situations in my last game. I play single, EA Niefel, high earth and nature bless, version: 3.10, map: Tempest 1.00, mods: Worthy Heroes and Streamers & Standards. I have also Epic Heroes active, but the game run in early ages.
Battle 1.
Commander died without being hit by either spell or steel. The battle report shows that one of my commanders died, but watching the battle I see both of them unscratched from the beginning to the end. Last killed enemy was a priest so maybe Holy Avenger spell hit him after "the movie" finished? What could kill 35 HP Jotun Jarl without leaving any trace (no magic on the battlefield except for some priests)?
Battle 2.
My Niefel Jarl SC was devastating 1000 man army of Ermor. He went berserk and did pretty well with his cold aura until he... routed. At least a message appeared "the armies of Niefelheim are routed" but my berserked giant was still fighting. Then Ermor started routing. The battlefield was almost empty. My giant was killing last soldiers and undead. Two enemy mages stayed with fatigue over 100. And then my SC died. No wounds at all, no enemy blow, no spell. Did I miss something?

If someone more experienced could help me to explain these situations I would be grateful.
To the 2nd battle I have a save if needed.

Thanks in advance
