Deathcap bug
I was in a game as twisted fate, I had 334 ap and then bought deathcap, my ability power only increased by a flat 120, it went to 454, but no farther. Deathcap passive said it was supposed to give another 120 ap but my ap listed was not increased and i did not feel like it gave me the 240 it was supposed to give me. Is this something that justa bug that happens every once in a while?
