I'm saying that if the problem didn't exist in the first place, it would make purges much less necessary. That is what the other thread is about. Do I need to post a link? It's in the same folder as this one.
Oh, sorry, I'm getting my topics confused... but this is still part of the same problem. If trade partners were closer together, there would be a lot more variety to choose from. The topic that I referred to is an idea to eliminate the abandoned positions by not putting them on the main map immediately. That would mean that only ACTIVE players make it onto the main map, and that would resolve all of the trade issues.
I was also saying that I have noticed a lot of people with boosted goods are trading for their own boosted good. This is probably only an issue at a transitional stage of development, and I think that the OPs problem is just bad luck with who happens to be active close to him. The actual positions probably have a very even distribution of trade goods. The ACTIVE people may all be trading the same thing... just bad luck.
