It looks like REF War Galleons after returning to Europe, will never return to the New World with the remaining REF troops, while there are still Man-O-Wars hanging around. The War Galleons are simply eliminated, the number of warships in the REF screen will suddenly drop. To resolve this, I used WorldBuilder to delete all the Man-O-Wars. The number of Warships in the REF screen dropped immediately to 1. Soon after, 1 War Galleon re-appeared to drop off some REF troops. After it returned to Europe, I got an Independence Victory immediately even though there are still REF troops in Europe. It looks like the last War Galleon is automatically eliminated when it returned to Europe. Does anybody encounter this bug?
