I've seen several threads on reddit and these forums about this issue from months agoo. I as an Australian love playing as Australia and trying to develop my home country into an economic power house. I have been playing Vicky3 since launch and at that time repeatedly ran into an issue where low shipping lane effectiveness from the British Empire refusing to build convoys completely crippling my otherwise advanced economy with NOTHING that I could do to fix this. I assumed this was a balancing issue initially and I had hoped it would be fixed when I came back the game. Alas, I was very much enjoying my run until the same issue happened. My main question is - is this an intentional decision that big empires will completely neglect convoys? As it is making it incredibly difficult to complete a game as my favourite country to play.
