Ok, I fixed my silly mistake. The hotfix is out with v 0.3.4.
One note about sandbox, one of the features of this mod is it transports players between surfaces when they walk over the special 'Staris' structures. I don't think that will work in for sandbox mode since the controller is not of type "player"
I may be able to do something about that, but it will have to wait till after I get the first technologies implemented.
