After almost a year, one of the two casino ships decided to start working. The other, same class and everything, is still nonfunctional. Annoyingly, the one that is working is not orbiting a colony (it's on Jupiter with my fuel harvesters) whereas the one that is not working IS orbiting a colony (a comet I've got my asteroid miners at).
I don't understand what these things are doing, and it's really obnoxious.
