Since U46 I am having an issue with mounts and pets not retaining the custom names I give them, and they are also sometimes not retaining status as a favorite. I don't really know how widespread of a problem this is, but Deepsea Corsair Summoned Steed is one example of a mount that lost its favorite status (and continues to lose it every time I log out) after this update and had its name reverted to default. I've played around with renaming a few pets in the past week and none of them have kept their new names, but I'm fairly certain that the ones I had named before U46 are unaffected.

I'm sure this is something that probably relatively few people will notice, but the favoriting system being broken like this is incredibly annoying when random favorite mount is your preferred mount selection option and your favorite mounts are no longer randomly showing up unless you re-favorite them every session
