I have four ebony horses which are branded on every freedom server and also cared for on all the servers by the same toons (been sailed around to all the servers, branded and cared on all).
This lasted very well since the cages were introduced until now when one of these horses suddenly died.
It appeared that ALL four horses lost the cared for status on Release (but still branded), sailing back to Celebration they still have the cared status.
The dead horse was Rafflegrey, venerable and the corpse still had the mark of the brand on Release server.
I dared not to sail ton another server to check the status, I would be really sad to lose more of them.
This is quite a disturbing issue as the venerable horses without the cared for status tend to die within minutes or hours.
