If you are having difficulty with the store, and it's not changing inventory on schedule (every 4 hours for version 1.00.04 and later), there is something that you can use to try to force a refresh of the store's inventory: go to the store screen and press the R key on your keyboard ('r' for restock). If your varied items have been failing to restock, this code should restore it to a normal schedule. Note: This will only work with versions 1.00.04, 1.00.05 and 1.00.09.
