I notice today, When you reload a game with Goblin camp Close to yours. It will turn into a stockpile. The bigger problem to this is sometime the game will spawn lots of goblins on reload if you have closed off your camp.
Steps to reproduce:
Save game with Goblin camp close and in sight
Load game and Goblin Camp still there
Load game and Goblin Camp is now stockpile. workers and footman with go to it and use or patrol it
