Two things: I am in Moab, UT and it just happened again with GCXK9D. It doesn't show on the geomap but it is in my GPS. Last log was a DNF from 11/24/17. Second, and maybe more important, I received an email from Geocaching Forum:
Hi substickers, Thanks for your submission! Before your content can be seen by other members, we need to create an account for you. Finish Submitting — Geocaching Forums

Clicking the link given takes me to the Search page, but from there it is not obvious at all how to find the place to create an account. I am a longtime member of geocaching.com and don't want my email to be deleted.
