Quest problem

[IckyJoelIdeaVole]

I've got a modding problem. What I'm trying to do is make it so that the Klakar require you to give up a valuable item before they'll trade with you, but I'm hitting a brick wall as far as how to implement it.

There doesn't appear to be any elegant solution. The best way would be to assign a tag to the items I want them to accept, but I can't find a way to remove the item afterwards. Sure, I could just have an event remove every possible item, but that'd make them get greedy if the player happens to have found more than one. I suppose what I want to do is make individual pages to check for each item, but every way I've tried to implement that has come out all buggy.

Also, I've somehow managed to break the Klakar entirely. Something I did makes them never greet the player at all, which is very upsetting since I'd already found a solution to that particular problem. I can't see why it would be happening now.

Anyway, here's what I've got. Anyone have any suggestions?
