Can only complete retrieval tasks, even with that the quest UI doesn't update to "completed" unless you go back to the previous page and then reopen the quest page.

Scratch that - User error. You need to exit the edit mode for these to work. Retrieval works in edit mode as well so that kind of threw me off. Thank you for an awesome mod! Ability to embed images and maybe even a trigger to play .ogg audio file on quest description / quest completion would make this even more awesome! Making voice narration possible,
