So, some rooms are generated when you enter them, or at random times. Like the markets and the badlands. This is great. It means we don't have 1,000,000 rooms sitting around.
However, what isn't good is that if you go @ooc from one of these rooms, the game will see the room is empty and recycle it, then you return and are in a recycled room object in a recycling bin floating in MOO nothingness.
We've blocked @ooc from these rooms. So don't plan on going @ooc from the middle of the badlands, or a market.
