My main issue with the quest chain as originally implemented was that the warning text was unclear, as Hurin has explained. Look again at Hurin's screenshot:

The warning only refers to quests bestowed by him that are currently underway. Like many others, I took the time to read the text, but failed to make the connection with the deed, or realise that there were further quests that Andreg had not yet bestowed upon me.
1. The warning text should at least refer to quests that have not yet been bestowed, e.g. "Advancing the quest will no longer allow Andreg to bestow further quests upon you and will cancel any quests bestowed by him that are currently underway" and preferably to the deed, e.g. "You have not yet completed all the quests that Andreg can bestow upon you. Advancing this quest will prevent you from completing the deed, 'Track an Old Goat'".
2. How about two buttons a. "Finish Now" and b. "Finish Later" rather than a. "Complete Quest" and b. "X" in the top right hand corner?
