I have been seeing this bug only in the last day or two in WvW, specifically Eternal Battlegrounds.
Hunters pets are able to bug through the door teleports on the enemy team and walk straight into the castle and onto the walls to attack the defenders. I have only witnessed the bug happening in Stonemist Castle and have yet to be in a battle anywhere else to watch if it is happening.
The pets are able to run through the gates and attack players or siege equipment making it a lot tougher to even manage to keep siege equipment to defend.
I’m not sure if this is a bug or not but seeing as it seems a bit unfair to defending teams and that I haven’t witnessed it before then I’m guessing it is.
I have uploaded a screenshot showing 2 polar bears from the enemy team, 1 assaulting the boiling oil and another heading towards it. None of the walls or gates were breached as the enemy didn’t even have siege equipment up. Sorry it’s not the best, couldn’t get much chance to amongst the chaos.
