Have encountered a few bugs, didn't affect me though.
So after i had joined the companions, and i went with skjor to the underforge to become a werewolf. When we entered, Skjor was stuck in the door, he kept walking on the spot, not exactly game breaking because i just left and entered again and it was fixed, but still a bug.
This one happened to my friend, again with the companions. Doing the first quest with falkas, he was told to go kill the bandits at Valtheim Towers, problem was, he had already killed the bandits in a previous encounter. So he cant complete the quest and hand it in, because the quest indicator is for the dead bandit chief.
Also, when i get smacked by a giant, my body went flying hundreds of feet into the air ^^ hilariously funny, but still a bug

Apart from these 3, the game has been pretty much bug free
