flying goobs?

i didnt see anything in todays patch notes but while out questing i mounted up via random flying mount and i got my goob mount was confused at first then i tried to fly with it and it actually worked, did they add this in todays patch? or has it been in the game and if so when did they add it

it was in the patch notes and it hasn't been a thing til today.

Behemoths, Goobos, Lavender Goboos . and I forget the other one .. can now fly.

Which is dumb IMO.

yep gobbue behemoth and the amaljia drake can fly
but sahagin mount still cant swim
