is it possible to have a button in the battle menu that reloads the girls? sometimes they dont even show up or they do show up but when you strip them the animation fails to activate
theres some automatic reload's in the arena area, as long as you wait a few seconds before rechallenging someone the live2d should come back (unless youre playing the demo)
i've never heard of the stripping animation not playing though, which girl did it happen with?
its actually been quite a while since my first play through of the full version when i kept encountering it, it just may have been me challenging everyone too fast, it could also have been because i worked out Kate's room code in the demo and jumped ahead thus messing something up
