Yes Susie,
This is a relatively new phenomena we @ the WGTAACC have been studying extensively. This condition, which we have dubbed " Avataris invisibilis " at first seemed to be limited to the Pinehurts course, but most recently appears to be spreading exponentially to all known WGT courses, after the disappearance of Oakmont. Rest assured, we at the WGTAACC, with the full complement of Team Yancy members, are on point with this and will keep all forum members informed of our findings.
Doc :)
