Actually after progressing a few turns, I've found some of these problems are linked. I have a fleet stuck in the seaway again, and a fleet stuck in the Admiralty screen. This is the same game, just a few turns later. - In this screen shot, I have a fleet stuck in the seaway with a 'phantom' ship that is or isn't there; it will not progress to Europe nor Jamestown (its on a Jamestown-Europe trade route). If this fleet is NOT selected and you mouse over it, it lists three ships in the fleet: a Ship of the Line and two Galleons. If you click on the fleet and select it, and then mouseover it, it shows four ships in the fleet -- the Man-o-War, plus the Ship of the Line and the two Galleons. This fleet also shows as being in Europe under the Admiralty with the Man-o-War, Ship of the Line and THREE Galleons for a total of five ships, though you can't do anything with it except to modify the state of the ships. Using a mouseover in any of these three contexts (in the main game map with the fleet NOT selected, in the main game map with the fleet selected, or in the Admiralty screen) indicates 'a convoy of 5 transport units is awaiting reunification with this convoy' which doesn't make a whole lot of sense, as I'm pretty sure it isn't two fleets of five ships attempting to unify. In any case, the fleet is stuck -- the fleet in the seaway won't move. I can't get it to go to Europe either, it just sits there in that seaway. I did manage to un-stuck it by cancelling the stuck-in-seaway convoy's automove and splitting it into individual ships, and sending each to Europe. Still, I think its worth fixing. For that matter, I hope the convoy auto-joining can get a bit tweaked overall to make it easier and simpler to add ships to convoys ... I can't quite figure out how to get ships to join ship convoys unless those ships are trading with Europe (so convoys of ships running between settlements, or convoys of ships auto-trading with Indian villages ... how do you get ships to auto-join those convoys?). Thanks, hopefully the problem I perceive and am trying to report here is comprehensible.
