Incoming MEGA-post! I have a few good ones to share.
In
Mass Effect Andromeda, I was fighting Archon's Sword and right when I used Biotic Charged she
teleported to a secret room the devs use to make her inaccessible in the fight. So naturally I tried to kill her in there.

In
Tales From The Borderlands I failed a sequence and when I started over two NPCs wrestling with each other teleported around the level causing their stuggling noises to loop:

In
Uncharted 4 I lined up a bad guy with my scope and right as I pulled the trigger, another NPC ran right in the middle of us getting me a headshot.

In
Dark Souls 3, a Hulking Knight somehow got himself caught in fire as he was patrolling and killed himself:

In
Far Cry Primal I sneaked up on a bad guy and killed him. The thing is, we were on a slope and he was higher than me, and the animation of the kill dragged us underground creating grassy skys:

In
Fallout 4 Curie turned into the Exorcist:

F4, I launched a missile into a room and when I came in a Milk bottle was spinning around on it's top endlessly.

F4! I killed a guy at the top of some stairs and when I went to collect the loot his head met me, as it was slowly bouncing down the stairs:
