There's an instance of Starbase Fleet Defence that, as of right now, has been running for 2 days, 16 hours, 57 minutes and 37 seconds. Anyone that queues gets put in the same one too, so it's making progress almost impossible (unless you're lucky enough that 15 people have filled it up so you can get into another one).
It's frozen in the first stage with no enemies spawning. Any chance of killing that instance please?
EDIT: I do apologise, I didn't see the other thread here:
