Getting on to the actual glitches, there are several I have encountered. (These all happened on my lightly armored thief btw, which I guess is why so many happened to begin with.)
1.A bandit with a 2h sword executed me despite the fact during the animation he was about 7 or 8 feet to my right and didn't even touch my character.
2.A dragon with literaly no red on his health bar performed the jaw execute move on me while he was being attacked by at least 3 guards with arrows, swords, etc. I guess it makes you immortal or something.
3.This one has happened several times: I would be running away from someone and then my character will lose the will to live and freeze up while the attacker takes their sweet time doing the execute.
Have these happened to anyone else?
