2 Things:
1) When leading the Czerka Twi'lek recovery guy out of the abandoned base on Telos, I had a terrible time having him following me, having to go forward, backup, tell him to follow me again, repeat.
2)I encountered a couple loops and breaks in dialogue, a couple with my followers and one(in particular that I'm thinking of) after fighting the assassins before leaving Dxun.
