Try getting out the other way?
There's two exits in that goblin dungeon, one leads into the sewers, and another (north side) leads into the forest.
Do you have save files for this? Its good for bug fix
By right, you should able to escort them out as long they are within the 3x3 tile of the exit, with you.
i had already saved over it, the only ones i have left are the ones i made when i was resting in a side thing in that dungeon, i dunno if its actually gonna be usefull though. is there any way to get them to stand up? waiting for them to actually follow me by brownian motion and bouncing off every wall while i was trying to not have to fight more goblins was infuriating
