So after annexing a country with a few provinces i got a little inrest but my situation was stable so i though i let them rise to keep atonomy down, they rose and i though ok, i have 110% discipline and my standing army and forcelimit is 12 and their 2 stacks are 10 each with 0-1 generals (i have 0-2) and both their stacks are in Grassland/Farmlands with same amount of cavalry as me. So this is the weird part: i attack and lose!!?? their armies merge after the battle to a 20 stack and walk out to a little island so i though now its over. block with my boats and unsiege the provinces they took so now they are trapped and demands ticks up to 100% so i thought its fine i just DoW that OPM that is gonna pop out and retake my core but when they enforced demands they took all the provinces (3 plus that island) of the country i annexed, despite just occupying 1.. WAT?
