All my creature companions have disappeared.

I had bought one earlier today from Auction House, it appeared OK. But i noticed I didn't have any others.

Just got a wolf as favor reward, claimed it, it appeared OK in stable. But one I bought earlier was gone.
Logged out, checked another character and no creature tab.

Logged back in with main character I claimed them with and no creature tab.

I didn't have many, likely just a bit over 10 or so, but now I have none.

No big rush, I don't really use them much, just wondering where my little friends have gone.
