Hey, when the potion peg is destroyed, there is no way to put a new peg where it was.
what do you mean exactly? the place it was becomes blocked?
When a potion peg is destroyed, it doesn't get replaced by a normal peg, there is just nothing there. This did happen in a pocket dimension if that helps.
its not meant to be replaced by a normal peg, its a one time use item you can place anywhere
