Hmm the option for the body types should appear when Sparkle wakes up after meeting with Wendy to make the decision on how to handle turning into Sparkle IRL. The variations should show up at the start of the second day of the ship voyage. I'll double-check the code to make sure this is the case.
Okay weird it's there now. Wasn't there last i played. Maybe the reset(on/off) jarred it loose. Thanx. Oh and Sparkle is one of the prettiest models I've seen in a VN
