All current shop owners using chest shops, please adjust your chest layout to ensure your signs are registering the correct chest.
If you stagger your chests and signs in a row, there is a chance that a sign will be linked to the chest to the left or right of it instead of the chest below it. To stop this from happening, use the layout below, where the signs are in a row and the chests are above and below them.
Additionally you can now purchase pistons from the admin shops.
