So after I close a shop to reset it, it says I need to get my items from Frederick even though I have room in my inventory? Is this supposed to happen or is something wrong
go see frederick in fm entrance and retrieve the items, after that is done u can open the shop up again.
When you close your shop, if it had any items in it, they'll transfer to fredrick and not into your inventory. Good tip is to drag all your items into your inventory befor closing the shop so you wont have to go to fredrick and you could open a new shop right away.
