Would love it if it would be possible to save the price of all kittys in a text doc, like you do with positions of animations, so you can just load it back up after a up date... dont see how it could happen but would save time so much
Low-prim mode, animations, sounds, etc, though, can all be sent from the old to the new on rebuild or update and could be stored in the Cattery for later retrieval.
Unfortunately, the price and whether it's for sale, or not, is not something we can access from scripts. So you have to make notes by hand.
