Since I'm still getting emails about this mod having dead links despite the steam thread I decided to edit the OP to include both v.10 (possibly stable but with fewer features) and v.13. To clarify and reiterate what I said in the steam thread, I dropped development of the mod on account of it having performance issues that I couldn't diagnose. Somewhere along the way I broke something, but since it was just a CTD I had no way of figuring out what it was. The process of removing things -> testing would have been too daunting given the volume of data I had added, so I walked away to work on other projects.
Anyone who wishes to resume development is welcome to do so. Consider this my permission, you don't need to contact me. V.13 in the OP contains all my dev notes and plans for the future.
If I had to guess I would figure that the crashes are caused by memory requirements being exceeded. For that to be fixed everything would have to be scaled back: fewer ships, fewer stations, and a restoration of vanilla commercial mechanics. As I found with the gold resource there are some things that can technically be modded in this game but in actuality making alterations to them causes fatal errors. There really is a delicate balance and if you attempt to upset it you cause cascading failures, as I seemingly did by attempting to optimize economic activity. In conclusion, I really don't think the engine was intended to be used for a mod that changed so much. I was extremely naive to try to push it in any radical direction, regardless of what it said on the tin, but I suppose that's hindsight.
Hot damn though, I had some great games before they crashed!
