EDIT: someone else posted this but you just upgrade the 3rd ability and it fixes it. Even if it says maxed for the 3rd ability, you can still upgrade it.
I just upgrade my roster to level 72 and two hero’s (Yasmin and Astrid) have one ability each that I can’t upgrade. They are stuck at 71 but when I click to upgrade it shows “maxed”.
Anyone else have this issue?
