Most of the newer mods reduce the number of freighters needed to stock any trade route (and remove CR freighters, which the AI never builds anyway). But the mods are all so sweeping in changes that I haven’t ever used one.
One day, I will sit down and make a minimal set of changes to SotS: removing/fixing detonating torpedoes (they don’t do anything!), making the trade changes, and removing VN probes (who are just annoying micro every few turns, and no threat, once you understand how to deal with them). Modding is pretty simple, it’s just time to sit down and work it out.
