So I wasn't sure if I imagined it the first time it happened so I tested on another class and confirmed this. -Find an AA with ENABLED or DISABLED that you want to upgrade and make sure it is currently ENABLED. Make a hotkey you can access easily. -Upgrade 1 rank, mode while keeping the NEXT RANK table open. -Toggle the ENABLE / DISABLE hotkey -The ability toggles, and you learn the next rank for free at a cost of 0 AA Please feel free to deduct -80 AAs total from my account I do not want to have any exploitive gains on my toons. Thank you.
