I do plan to try and redo Tara's quest (it was so close to the beginning that I didn't save, oops!), and I plan to keep looking with the other two. I'm going to chalk the freezing up to an unhappy run of bugs, because it CAN happen (happened on my own playtest for my own game, and everything was set the way it needed to be for an interactive object), but wanted to point it out since both times it was in the same space. I figured I'm missing something with the other two, but I'm just not sure what to do or if I did something too early and broke the quest for both of them.
