Hey Silver, glad you're enjoying the mod. That's not an issue however, that's how it works. You buy your ships from that station, just like in the base game. We used to have the shipyard in skirmish and then Golans on top of that, but in addition to being easily rushed, that would make base game skirmish maps incompatible, which was especially important with the period after multiplayer was re-enabled but before we learned putting new maps into a compressed meg file would stop them from desyncing every time.
