The last two times I have assaulted gobbo fort, the first awesome fight on the walls was bugged. There was no one on the walls, and only 5-6 *spoilers* inside on the ground lvl. The rest of the mobs inside and out were as normal. That fight is the second most amount fun you can have in an unspiced quest area unspiced, please repair!

Possibly caused because someone scouted far ahead of you causing the spawns to be absolutely minimal. Seen that happen as well.

Back to you, Bob.

There was no scout. And it wasnt minimal spawns, it was effictively no spawns. None on the walls at all and a handful below.
