[BUG] Items not being removed from the shop after editing shops.yml

[Gabo6480]

Describe the bug
Removing an item from the shops after its price changes least once it does not remove them from the shop in game. Unless you delete it's data from the database, or, delete the database file.

Steps To Reproduce

1. Add an item to the shop.
2. Buy/Sell so its price changes.
3. Stop the server.
4. Remove it from the shops.yml
5. Start the server, the item is still on the shop.

Expected behavior
I expect that If I remove an Item from shops.yml it won't appear any longer in the shop.
