BeetleGeorge said: Seems to be a general error I first noticed yesterday. First all my 5* above level 300 had leveling costs of 1 iso. After leveling the next level up cost was displayed with at least 5800 iso. E.g. Kitty had 6510 iso displayed for leveling from 393 to 394. Today, I don't remember exactly, it showed something below 4000. After leveling up it again showed more that 6000. Seems recently one should only do leveling up one level per day or it gets extremely expensive.
