just went back and tested it that is the cause doing the same thing (using hope on turn 3 and getting hit by as many stars as possible) caused it to happen again, it also causes some funny test bugs
ok, thank you for being incredibly specific, I will be updating this fight within the next two weeks (I hope), (changing the placeholder CH5 shadowcrystal attack, modifying dialogue a bit, making a longer ending scene, adding an option to nerf stars, etc.) and should be able to fix this
