My view on bots vs belts discussion. Logistic bots now cost... space science packs to craft. Exact amount required is defined in startup Mod Options, default = 20 (50 bots per rocket). Also, to allow personal supply by robots you get a small amount of free bots for every logistic-related tech researched (default 10 per tech, can be changed in Options).
Small changes concerning balance, gameplay, or graphics.
