Bug: The Subject S quest chain appears to have gotten stuck in between "Escort Subject S to Safety" and "Defeat all the Laboratory Security Golems". Subject S and the test subjects are just standing outside the Tunnel Access Delta PoI and have been for over two hours now. The security golem model is standing in front of them, but it is not targetable, and can not be interacted with. To my knowledge, this event chain is not tied to either of the map's metas, so it's not being held up by them. I also checked that the first event "Free Subject S by Destroying the Shield Generators" wasn't up. The test subject who starts the chain seems to still be locked in his cell and has been for over two hours, presumably because Subject S is already loose.
I did not actually see the event become stuck, it wasn't working when I got into the map, with other players complaining about it in map chat. I did investigate and attempt to kickstart the event by getting nearby neutral mobs to attack the skritt and also by applying buffs to them, (I've sometimes seen those help move stuck events along) but there was no effect. I tried to get nearby creatures to kill the test subjects in hopes of having them respawn, but I can only get one hermit crab to hold aggro and it doesn't deal nearly enough damage to kill even one of the test subjects.
I was unable to confirm if the issue existed on other maps. I've rarely seen Sandswept Isles have an overflow map, so finding another map to switch to is difficult.
