I found a bug during the Andothren Thieves Guild quest "Good Fences, Good Neighbors". The bug is regarding the NPC "Three-Eyes" that you have to recruit as a fence for the guild, whenever I tried to approach him my character would freeze up, but not my game. I could still access my inventory and the menu screen too, the music didn't stop either. When trying to speak with "Three-Eyes" you are also redirected to the previous dialogue box with the bosmer pawnbroker at the last stage you left it instead of accessing "Three-Eyes" appropriate dialogue box. Finally, I tried shooting at "Three-Eyes" to see if I could complete the quest this way, albeit unsuccessfully. When I shot at him with my daedric (demon) bow and iron arrows my character'smovement froze but I could still shoot him to no damage, and curiously my marksmanship started climbing up steadily until it reached 100. This is a pretty funny bug tbh, but it completely breaks the Thieves' Guild questline in Andothren, therefore I marked it as a critical bug.
