Yes, this is an issue already in live game. Have a family share and, in a moment of laziness, whilst leaving a clan mamber in my clan, Admin-swapped to the Admin clan to sort out some player shenanigans. When I swapped back to my clan, ALL pets and thralls had despawned.
On testing, my clan-mate placed new thralls and pets and I repeated the admin-clan swap and lost no thralls/pets. Just to make sure, I placed some thralls/pets and swapped back and forth and lost only the followers I had placed and not the ones placed by Clanmate.
Basically, Followers, and now Treasure, are linked directly to the Player name that placed and not to a Clan if a clan exists. This makes sense as it could be exploited I am sure. Not technically a bug, but something to keep in mind.
