At a particular location where Swen had some difficulty involving goblins.
I set up my party in a file to sneak round the back, with the mage at the back, but all were out of sight as far as I could tell. Lead character is spotted by a goblin, fare enough. However the mage gets dragged out of cover and into the target area. Being as robust as a chocolate teapot this did not go well. In general I think that cutscenes should only involve the character who first triggers the cutscene.
