I am learning how to use the quest system for my colony, and am testing the creation of quests, I have created a few test quest givers a few days ago. I deleted the in world quest givers named Test because the quests I was testing were either not right or I was making basic minimal not permanent quests just to see if I am understanding how the Quest system setup works.
I also had an issue a few times where I repeatedly got this error message when clicking on the quest giver: ERROR in Complex Menu Script v0.18.0: Dialog Script. Incorrect menu format
I didn’t mess with reporting it at the time because my test quest helper was needing to go to RL so I just had rezzed a new one a couple of times. If someone could remove the test quest givers from my My Quests page that’d be awesome, but I would also like to suggest that they be able to be deleted from the website so that we don’t have to pester anyone for help with their removal in future. 
Thanks in advance!
