Dolls

All dolls have a sell price of 0. Is that meant to be like that?

It's because they are in the Casino's Token Exchange and since they are exchanged for tokens, the gold price is set to 0 and the system won't let any item be sold for more than it can be bought. I've tried to find an easy way around it, but it's going to take some changes to the shop system to fix it and I don't think it's important enough to focus on right now.
