Out in the wilderness late one night near a bandit camp that I was spying on before my ambush, I saw what appeared to be 2 people fighting, one was using Fire Destruction and the other was using Frost Destruction. This was an epic battle to the death, a fight between an Arch Pyromancer and an Arch Cryomancer. This led me to believe that their may be disfunction between the evil wizards of Skyrim, I mean maybe the Arch Pyromancer stole the Arch Cryomancer's sweet roll idk. But it was a pretty epic fight and I was rooting for the Cryomancer but sadly the Pyromancer won. So I did the good deed of killing him at he was weakened in the fight and proceeded to loot both of their bodies.
Ha - I saw a variation on this - a senior Vampire vs. a junior type vampire, out west of whiterun, in the hills. I have noticed, when wandering at night, that there seems to be more things going on. The ranking guy won, but since he was down in health, Lyds and I dispatched him quickly.
I think 1.5 did introduce some random non-gamebreaking, yet sometimes amusing glitches. Not too far from the aforementioned vampire battle, as we walked westward, a mammoth dropped from on high, trumpeted in pain upon landing and promptly keeled over.
But the best one of these glitches was when I was walking along a road after clearing out a bandit camp (the one you go to to find Kharjo's amulet, iirc). I come around a bend and WTF! A giant and a painted cow are just... there. Then the painted cow suddenly bolts, running toward me like a bat out of hell (really, at an increased speed rate) - it runs down the road and disappears. The giant, meanwhile lumbers along, so I step back away from the road, giving him wide berth. He's looking at me, but not aggressive. I step back, staying along the waters edge to give him a wide berth. He ambles along for a bit then
slingshots about 15 feet of the road to the river's edge and
vanishes in front of my eyes.
Maybe I should not have drunk all that mead.
