I struggle to imagine how I'm going to fix any of these. I don't use colonies so I don't really understand how they work in the first place so I fear I'd find it very difficult to understand what I should do even if I find the codes responsible. TBH, I'm not even sure how one establishes a colony. (The whole concept seems a little nuts to me - if you're struggling with gold so much you need to turn over some of your territory it seems much more prudent to simply increase the amount of gold you're bringing in or pull back somewhere else... the whole goal of the game, the way I usually play it, is global domination so at what point does purposefully letting go of a part of your nation fit into this plan? I equally detest vassalage and have it off in all games. So I'm really probably not the guy to look into this!)
