What's the issue? Please include any error messages you receive and as much detail as possible.
I purchased one gb from a person, that went as it usually did. No problems with that. But when I purchased a cub sex changer and checked in my hoard, it was gone. I reloaded a few times and it still wasn’t showing up. It was only when I checked my user history that for some odd reason, instead of buying a cub sex changer it made me purchase a beetle slot

Any links relating to this bug? For example, if a particular lion is bugging, what is the link to that lion?
The male cub I was going to use it on was this one

It’s an I cloud link to show my user history
