Royal Robber - Is this quest broken?

[reichter]

Hello,
I'm at a point in the game where I'm not sure if I simply haven't discovered how to resolve the quest or if it's broken and I'm permanently stuck. So far there are several side quests in Riftland that I just can't complete.

I've been playing since day 1 and I know certain fixes are only applied on new games. The next main quest is Royal Robber and I need to find some evidence. I think I need to click on a skeleton next to the kings palace but my character can physically reach it. Have I reached a dead end and need to restart or is the solution elsewhere? I hope it's not bugged since I've probably spent over 60 hours playing this wonderful game. Any insight would be appreciated.

Thanks
