Ah! I see what you're saying. So you go to the shop, buy everything. Then go back to the world map, select continue building, and re-enter the shop.

There were a few issues. One issue was that I wasn't clearing callback hooks when entering the island edit mode. For most things, this didn't affect anything, because callbacks are generally not invoked when there isn't another island. But the shop registered an on-fadein callback hook, which was being invoked, and re-launching the shop.

Additionally, I've changed the shop script to convert the shop map location into an empty map location when you buy all of the inventory, preventing you from returning to it.

Currently, there is an enter shop sign, but no shop. The gameplay problem is solved but there are some graphical glitches.
