Guild Wars 2

When in Bloodstone Fen after gliding your loaded pet usually swaps.

100% Reproduction.

To Reproduce do the following.

Open Pet Management
Select Jungle Stalker as your primary pet
Select Black Bear as your secondary pet

With Jungle Stalker loaded glide around using your new gliding abilities.
When you land you will note that your default pet has swapped to Black Bear without your command.

It is possible that some of the new gliding abilities are causing the swap command to be called accidentally since this ONLY happens in Bloodstone Fen.

Confirmed.

And my Warrior changes weapon set each time after gliding in this map.

It’s the same for any Engi Kit that is equipped. It seems they simply do not save the information for our chars for this map once entering gliding and then exiting like they do for any other map in HOT or Core Tyria.
