I've figured out what happened. The romance was stuck because I had not completed the Burwood quest. The keep problems were stuck (I think) either because I had not completed the Burwood quest or because I had the planar sphere. I went to the keep, but did not get the Burwood quest. The keep quests and Nalia's romance were stuck.
I then loaded from before I got the planar sphere (figuring that was the problem). I went to the keep and got the Burwood quest immediately. I finished the Burwood quest. I finished the keep quests (little confusing there, as Isea kept on talking about how his father's invasion failed when it hadn't happened yet). I have just gotten the planar sphere. Everything seems to be going fine.
Summary. For some reason, getting the planar sphere before getting the Burwood quest or finishing the keep quests caused the Burwood quest dialog to not happen automatically (didn't try talking to the dude, because I didn't know what the Burwood quest was).
Things that need fixing:
Fix the planar sphere from interfering with the Burwood dialog when the keep quests have not been finished.
Prevent the Burwood dialog from happening before the (second) keep invasion (the one by people, not trolls) so as to prevent conflicting dialog.
And yes, my game is fine, but only after finishing the keep problems and Burwood quest before getting the planar sphere (as opposed to getting the planar sphere first).
I apologize if anything in this is untrue or insulting, its just the way I saw things.
