Perma stowed pet
Yes I have. I could not unstow it in PvE or WvW. I could in PvP. Was very weird.
Was able to reproduce this problem for Beta characters. It seems to be caused by the fact that the HOT pets are not valid selections for PvP.
Create new druid. Set both pet slots to core pets. Go to the PvP lobby and back to Silverwastes. Result: Pets are both present.
Set one of the pets to a HOT pet (doesn’t matter which one). Go to PvP lobby and back to SW. Result: Active pet is set to the core pet, and the other slot that had the HOT pet is now blank/unselected.
Set both pets to HOT pets. Go to PVP lobby and back. Pet is now perma-stowed and no way to get them back. Can’t open the pet dialogue box with the keybind. Changing maps does nothing. You pretty much have to delete and recreate the character.
