I know this was posted on the other thread, however this is getting really annoying.
When I have low stock (waiting for others to sell to me), and a buyer comes. They can buy the item, but all the information about the items (such as price, item, quantity, etc.) gets deleted. I have to constantly redo my shop, because of disappearing signs, and it is quite annoying. We really have to change this now.
The counter argument to this is it is more user friendly. How many times have you had to visit 5 different shops to find an item, only to find them out of stock?
If you have to redo signs, that means you have very little stock to begin with. If it is annoying for you to have to redo the signs all the time, it is even more annoying for other players to click on those signs to find you have no stock. This should encourage people to either hold more stock, or have less chests in their shops. Both should be a good end result for people shopping.
I know you have a lot of different chests in your shop (most people do not have that many). Perhaps keep a list on excel to keep track of your item prices?
