Potentially Wild Edit Reference
A wild edit happens when using the Creation Kit to edit plugins and an objects ends up in the middle of a worldspace with a position near zero.
In case of the Tamriel worldspace, such an objects floats above the Bleakwind Basin giants camp west of Whiterun.
For other worldspaces such objects might be just buried underground and thus not visible.
Look up the form id in xEdit and remove the reference, clean the plugin afterwards. Notify mod author.
In case the reported reference is not a wild edit, make a post about it on the official DynDOLOD support forum.
