Basically I evolved my Zabimaru Renji to lvl 2, but still have the effects of the lvl 1 evolution, how does that even work?! Do I have to do something else? it worked fine from lvl 0 to lvl 1... here is a print of the problem I'm talking about.

Hopefully its just me missing something, if not, this bug just wasted me some hundreds of vit to get the mats for him :c
