Try turning on Fast AA Purchase or whatever it's called in your in game settings under General. You might be lagging and the click not registering or something. But since you do get the popup, the plug in is working so with fast AA purchase turned on, it'll buy them without needing a confirmation box.
I thought of that yesterday but instead I switched to BRUTE as she only has a few more left.
To my surprise... Brute purchased all in "Special" first!!!
Now, with hundreds or even a thousand AA to go before max (11280 now) she has all the Glyphs!
I'll activate fast purchase and see what happens.
UPDATE:
Activated Fast AA Purchase and nada.. soon she had 75 AA built up and wasn't buying anything.
I could see "Attempting to purchase SO AND SO AA for 18 Points" but no purchase was made.
Digging deeper I did /aaspend status
Brute mode: Off
Auto mode: ON
Bank: 30
Should be working...
Then I did /aaspend to look at the options.
I see distinct command for Brute mode on|off|now
I see distinct command for Auto mode on|off|now
So I'm thinking.. doing /aaspend brute off may not actually turn Auto on.
Did "/aaspend auto on" and waited for next AA ding. Sure enough. She bought SO AND SO AA for 18 points.
Now it's three AA in a row she's bought without problems.
Just something to look out for.
Explicitly do "/aaspend auto on" when in doubt.
