In regards to lilith's shop her shop background file is not present in the demo. Also it seems your attempt at randomizing the quantity of the inventory in lilith's shop in the demo has also resulted in crash and display bugs occuring whenever the shop fails to roll max quantity on inventory. In particular items in lilith shop failing to display their card description only to suddenly show it on the wrong card when you select the card to the right. These blank card descriptions also cause a further bug where you can go further to the right of the right most card in lilith's shop with keyboard arrows to reveal a disjointed card description that will crash should you attempt to buy it.
A.E.R.A. is doing 0 direct damage in the demo and can only indirectly inflict damage through burn and bleed. She's healing through life drain as though she's inflicting damage though.
Menu seems to randomly load up other MCs sprites at seemingly random intervals. When I created a fake boob char 16 file to fix the menu crash it also happened to inadvertantly fix my boob MC that had long hit max size for display. This issue with missing max MC size portraits in the demo is probably due to it looking for portrait lvl 16 instead of 8 as it should be, but for some reason its not erroring for failing to load a missing file.
