This is about those moments when your game just Freaking hates your guts and pulls a [censored] move.

I was at the end of The Only Cure when after killing the boss, I was greeted to a wtf moment when the boss slid down a small crack in the floor and making impossible to try and get the key out.

Ouch. Painful! Did you have a save just prior?

Yeah I can totally relate right now, I had to do Rising At Dawn earlier today at level 23 so I could continue with the Dawnguard quest. But for some reason Falion instead of being in his house at 6pm like he's supposed to be according to the Wikia, I'd leave the inn after that time and find him walking along the road toward his house, and not only that; when he went inside his house it was locked so I couldn't go inside with him. (I could pick the lock but when I tried that he threatened to throw me out). No good at all when I want to buy a black soul gem from him.

They are people too. They don't always obey the rules any more than you do! One day....as AI improves you might go there to find he's moved into a mobile home on the edge of town and retired from his day job
