Yet another bug. Shyka the many.

[Hateraide2011]

I got the crown pieced together and went back to the NPC. I told him what I want to do with the crown, and the dialogue option ends. Nothing happens.

This is a bug, but there is an easy workaround:

After you kill the Linworm, don't loot the corpses until after you have spoken with the named NPC that helped you with the fight. Complete his dialog, then loot the corpse. If you do this, all should be well.

It seems the issue is that the NPC has an alternate dialog tree if you've completed the First Crown prior to talking to him, and that alternate dialog isn't loading properly. If you haven't completed this alternate dialog tree (which you can't, because it doesn't load properly) then the interjection from the NPC when talking with Shyka doesn't work properly, so Shyka's dialog aborts, and you end up with the bug.

Thanks Mreed, the workaround is successful you saved me a lot of headache.
