So I messed up as Poland and can't form the Commonwealth because I gave Lithuania too much Russian territory. Since PU doesn't seem to have a "seize land" button like vassals the only way I can get territory off of Lithuania is to lose it in a war. With that in mind I declared war on Muscovy with intention of losing. After 1 month and me being allowed to send another diplomat I tried to offer them 2 territories for free and they won't take them. I have to beat them up for a while to convince them to take my territory. This take "Shut up and take my money!" to a weird level. Btw, aren't Paradox threads amazing?
