As I said earlier, the cabin, while often being present, is not a guaranteed spawn on a map. As such unless you can get it to happen again and post the exact debug message here, I’m going to assume that the problem is the one that most fits the symptoms, that it simply wasn’t able to find a cabin on the map to put you in. It’s not really something that can be “fixed” other than by making scenarios check that they can actually spawn at a location prior to allowing you to select them.
