I'm experimenting with placing a new LayDownMarker in the Hotsprings Camp (Tamriel Cell 27,-7) and I can't manage to get it to work.

I've duplicated the existing marker, moved the duplicate to a new place and can't find it in game.

I've adjusted the height of the marker thinking that the PC may not be able to access it, but that doesn't seem to be the issue.

Is there some other object I have to duplicate or some other trick I'm missing?

Apologies for what must seem like a basic question, but I'm only new to the Creation Kit.
