Ah, that makes sense. It's certainly not a high priority; I was just curious if it was intentional. I have a suggestion and a bug to report. I was going to send you an email, but since we're talking here anyway...
First, when Billy asks you to bring him 50 units of food for the "Papers please" quest, I was very confused, and it took me a while to figure out what he was asking for. I tried cooking 50 hard tack, and 50 meat, but he wouldn't take them. I think it would be more clear what his request is if you phrased it as something like "come talk to me when you have stored 50 units of food."
Second, if you enter the easternmost beach cave at night, then leave, the outdoors will be super dark. Entering and exiting another cave fixes it. I thought that this might be the case for every cave, but the kobold cave doesn't do this. I also thought that maybe it's just dark caves, but I checked the mine and it also didn't do it. So, it may be just that one cave.
