Timmy is to blame

I am playing two different synereo of the game. One where I jump right into the main quest and the other where I completed over a dozen side quests and a couple activities before I even met up with nightingale. Game has played great no crashes, quests play out, I am able to gain experience in both ways until Timmy. Once I talk to Timmy it bugs out. I can handle the scenery hick ups and the other little glitches, but when you can’t initiate quests.
