It happens to me the same think my last payment was lvl 72 1,800 necros and after I reinvest them it pay's again at lvl 61 800 golem's 170 warlock .

I didn't took back ut list the investment I did.

I have one suggestion for you Mihanicks of stormfall utlist provide in the game ress bar to show people  how much exactly must to invest for each lvl to feel up this bank of yours or maybe you mean by the word bank the money we spent in this game !!!!!!!!!

Any way how I see your forum doesn't has the potential or you management of stormfall don't give a shit excuse my language but we play this game to enjoy not to get pist off every time we open our phone or tablet.

Respect above all !!!!!

Have a nice day
