I am in the exact same spot, although I finished all of the quests under Troll Trouble, all of my Companion Quests, and the Misc ones at the bottom. I believe I am waiting on that time that talks about the next event happening on that one Hill. It should be one of your Kingdom Quests (forget the actual name).
This is my first playthru, though, so I may be completely wrong. I have been meaning to look it up to make sure I am not doing anything wrong! I was going to take the time to explore the map as much as I can, claim some resources, and do some Kingdom quests with my main character and other advisors. I believe I am all caught up and waiting on that timer.
EDIT: I should say on difficulty, I am just on Normal also. I sort of like that challenge level, though, and don’t like to push my challenge in games like this. I am still running RTWP and pausing to select spells to cast periodically, and that is working well. I love turn based, but haven’t turned that on yet. It sounds like normal is a bit on the easy side for most of the game, though. I just keep it there as I like it to be a little easier.
