Minions/mounts (from Patch 6.5) periodically disappearing from Lodestone profiles

Details:
Some minions and mounts introduced in Patch 6.5 periodically disappear from Lodestone profiles and then reappear when profiles are updated again (appearing as if they were just obtained). I've personally observed this only with "Wind-up Golbez" and "Vicarious Vacationer" for minions and "Garlond GL-IIT" for mounts. Older minions and mounts seem to be unaffected, as well as several from Patch 6.5, but this list is likely not exhaustive.

Steps:
The bug occurs at some point after these items are added to Lodestone profiles initially. They appear for a while after you first get them and then disappear later. They're still present in-game, but are erased from Lodestone entirely until the next profile update.

Date & Time:
Observed around 2:00am PDT on October 8th and on October 4th (the day after the patch release). The first instance was less than 24 hours after the patch launch and the second was around 72 hours later.

Location:
Numerous Lodestone character profiles.
