After restoring Classic CatPika with the refinery, she's suddenly crystalized and bitmap, but there's nothing I can do about it. Luckily, if we keep the CatPika history from changing and making modern CatPika crystalized too. When she was first out, she didn't show signs of crystal, but then it appeared. Apparently, being restored after getting frozen while hearing the original Lavender Town thing does that... Credit to @supercoco142 for the tutorial and original.
