Baby trader llamas disappear immediately

Breeding 2 adult (tamed) trader llamas will also cause the baby trader llama to disappear. Also if a trader llama spawns as a baby without right-clicking, it wont disappear. They will also despawn if using the /summon command withe the {Age:} tag.

Still happens in final 1,14.2, please reopen. Breeding trader llama spawns a baby that immediately despawns afterwards

EDIT: Nvm so its future version, not 1.14.2?

Yes. Still seeing in 1.14.2. First thing I tested. Fed my llamas two hay bales and heard the baby cry once, but it never appeared.

Concur - Ticket needs to be reopened as issue has not been resolved in 1.14.2
I just observed same behaviour as reported by @Ozone and @Jeffty.
My world is single player, just upgraded from 1.14.1 to 1.14.2, after which I tested breeding, which failed for former trader llama's.

The bug is still not fixed.

Mine don't despawn until after 40 minutes, 20 minutes to grow up and then I have 20 minutes to tame them which stops them despawning, 1.14.4

After closer obvervation that's correct, I see the baby, then the adult, but the adult disappears after 1 day. I even tried name tagging the babies to see if that would work, but they still disappeared

This is intentional. Trader llamas will always disappear after a certain amount of time.

even when name tagged? and bred? a name tag mob despawning seems like a bug

Yes.

Also note that this ticket is only about the trader llama disappearing immediately after it has been bred. That issue has indeed been fixed in 1.14.3.
