im level 127 and i've gotten my total AP all the way to 165, but twice now it has dropped down to 164 and i've used an AP to get it back to 165. i just now bought another AP up to bring it to 165 again (i like keeping my AP as multiples of five), so this is the third time where my total AP is 165. why does it keep doing this? does anyone know why this is happening? or is it just a glitch im going to have to live with?
