I've got the first Hub gates aligned, and I'm having CLS2 ships collecting equipment for my future fleet (shields etc.) and bringing it there. I have the HUB set to not allow NPCs to trade (though they sometimes seem to dock anyway). Problem is, my universe traders keep trying to buy or sell things from/to my Hub, messing everything up. When they try to sell things, they just sit there forever until I notice them, since I've not given money to the place. Money lost. Worse is when they come and take away gear I've been stockpiling. How do I get them to stop? If they were CLS I'd just set my Hub as blacklisted, but I don't think I can do that with UTs. I believe I can get them to stop either buying or selling with the "Product Selling Price Setting" by jacking it all the way up or down, but won't they then be even more likely to do the opposite? They'll see a high/low price and try to sell/buy even more, no?
I didn't find the right solution from the Internet.
