On multiplayer servers, the waystones players make can start to build up, and if a player accidentally activates one they didn't intend to, they're stuck with it in their list. Breaking the stone would solve the issue for them, but cause a headache for anyone else who actually uses that point.

Allowing for another option in the waystone menu, perhaps off to the side, for a delete mode that can be toggled or only allow one delete at a time would solve this issue.
