Finally caught a pesky saving/loading issue with the shelves. Apologies that it has taken this long, but now it should hopefully be solid, and potions should load on shelves properly!

???? Saving / Loading not working for shelves that are upgrades
✅ Potions not properly placed in shelves, just spawned on the shelves (but not attached to the shelves)
???? Potions lost on starting shelves occationally
