Is there such a thing ? Walls I don't mind so much but I'd love to lay paths once and then stay there
Paths do not deteriorate, they can be hit by lightning if no rod is available to catch it. Fence decay can be disabled using CJB Cheats menu or one of the stand-alone unbreakable fence mods.
Paths may not deteriorate, but they do have a habit of popping off when you walk over them. The tile does into your bag to be set back down.
