Trading issue/Buggy Game

I really dont get how people play this game because I just have a bad time everytime I re-install this terrible game. Few months ago iit was an endless control unit issue which wouldnt go away, now today Im trying to re-learn it and I have 10 donky/traders just sitting idle while im attacked from all sides that will not physically do a command or actually trade.

How after all these years its still such a buggy mess of shit is beyond me. I wish i never tried this game
