Some bugs to report and a comment or two.
Bugs: Nations seem to go to war even straight after selecting an option to pay them off the turn before. They also go to war the turn after peace was declared and a peace conference was finalised.
Dissolved nations sometimes only dissolve their ports, but continue to exist as land empires. I ended up at war with Austria-Hungary, their port provinces dissolved, but I remained at war with them and could not end it as there was nothing to invade or sink. Their land invasions also seemed to freeze.
Primary and secondary weapons and torpedo's still not tracking and engaging regularly. My experience is that it is predominately aft guns on light cruisers, other ship types seem to be less effected or not at all.
Comment: I think there should be a truce period after a war concludes, making it impossible for two nations to go to war for a period of time after declaring peace, or at least making it vastly more difficult (make the tension requirement double for a period after the end of a war for example). My experience so far is that a few turns after declaring peace, they are threatening war again. In each case, they are at war with someone nearby and sending their ships through my waters. I don't think this should be happening, or at least no where near as much as it is currently. Alternatively, have fleets cause tension to rise only when stopped in a nations waters, not sailing through, or at least delay the start of tensions for a turn or two. I think there needs to be some distinction between passive transiting and actively warmongering.
After all, a fleet setting up shop in a nations territorial waters and where it is not supposed to be is far more threatening than it mealy passing the coast.
