While adding tags to post #1746440, I initially put the tag "looking_at_another" in, but I replaced it with the more relevant "eye_contact" before hitting the Submit button. However, "looking_at_another" still showed up somehow, even though I did not save it separately before doing the rest of the tags. Deleting the tag itself did nothing, nor did deleting it and saving additional tags at the same time. I never recalled having a problem removing or altering tags before, and I was wary about using the "Undo" or "Revert To" options, since I am rather new here and do not know if that could mess things up further if something is actually buggy. Is there something I'm overlooking, is it a member-level thing, or is something amiss?
