I came across a dragon statue that leads to one of the parts of the "The Lost Eye" quest - the first part involved finding a camp.  At that camp, someone wanted to sell me info on where the eye is for 20 crystal.  If I say "I'll come back later if I'm interested" (because I don't have 20 crystal), it says I need to go back to the statue later.  If I then go back later and again click the "I'll come back later if I'm interested" option... the quest spontaneously finishes, and I get the dragon eye (along with text referencing a character I have not yet met named "Arneson").

Presumably this is a quick fix - just make the quest status stay the same instead of finishing when that dialog option is clicked.
