Hi, I hope I can make sense of this... My main pet has 722AP. I have tried to use all his AP, but am able to get 630AP used in the scrolls I choose for him to stay put in set. Then when I try to add more scrolls and click Edit set - it goes to: Current AP Value: 0. -_- Is there a certain way one has to choose their scrolls before clicking Edit Set? and no I am not trying to add more scrolls, then He has AP for. Any assistance, will be greatly appreciated. :)

Sounds like a bug. I would either file a ticket for it or post in the Site Functionality Issues section of the Problems & Bugs forum. Best of luck finding out what the issue is.

It sounds like your pet is too smart for the scroll system :p I would file a ticket. The admin may also ask that you make a post on site functionality, depending on whether or not they could fix it.
