As I wrote earlier, the plugin detects monuments by the "Monument Marker" prefab, if you move it to the center of the Bradley Arena, then the monument will be detected in the center, for this you just need to delete the file with the coordinates of the custom monuments before wiping. As for the custom location, I use monument markers with the same mark to mark them on the map, the plugin detects only one of them because the marks are the same. If you delete that monument marker, where the monument is defined, then the plugin will choose another custom location. I will not delete the monument markers, but you can edit the map, so everything is in your hands
