I get an SQL error every time I try to buy a new skin from the shops. So far it's only the skins that seem to have the issue.
I did notice Monkey had an SQL error, but her's was with the refueling station and was fixed so I didn't want to feel like I was spamming it since this is an error showing up in the shops.
If I find another item that triggers an SQL error, I'll update this.
