In my last battle in coliseum I barerly reached 80% of Tier 7 and wanted to upgrade a character but I it seems that I didn't get 800 of MK3 Esk Ability Module after that battle.
Usually I wouldn't notice it but I improved of 3% in coliseum and reaching 80% should allow me to improve a character to the next level which I can't because I have only 125 of MK3 Esk Ability Module after the battle instead of 925 pieces.
