I have noticed several users pictures disappear over the past week. The three I noticed were scottsigler (FD∅™), I AM— (MC), & deathspiral (MC). Scott has since replaced his. I AM & deathspiral’s are still missing. I don’t know if this is a gremlin in Drupal or what. Figured I should bring it to your attention since it is no longer an isolated incident.
If you are a user who has had their picture deleted (and you didn’t do it), please post a comment here with any details you can provide. Thanks!
