Soo this happened to me 2nd time
After level upping some toons i saw almost all of my coins gone. At first I thought I misclicked and bought food with coins and not with gear markers. But today during level up I mostly used Food Bags from War Stash and again my coins were gone. I think I saw someone complaining about this here some time ago.
Is it really that hard to fix basic bugs or are they too bussy in creating more stupidly overpowered premium toons?
