I completed the Seasons of Silver with a bronze medal, during which I restored the hacienda and got the cargo ship reward and built trading posts to the other islands. From reading other posts, these should carry over to the next try. However, I cannot restart the scenario so that I would receive those. I only get a completely new game, which creates its own save game. I restarted once a while after playing the scenario, which created a "Vasco Oliveira 2" save, which I used to complete the scenario. Now if I restart the scenario, it creates a "Vasco Oliveira 3" save (and then "Vasco Oliveira 4" after that). I tried deleting the other save games (besides the #2, which I used to complete the scenario), to no avail. I have not pushed the "Reset scenario" button even once. I have tried to load a save game before the scenario completes, but it only allows me to go to the main menu in the victory screen. If after that I use the Scenarios menu and push the Begin scenario, it always just creates a new save game, with the hacienda in ruins and no other trading posts. The scenario loading screen shows the bronze goal as completed.
My only hope now is to push the Reset scenario button and try if the next time the progress starts to carry over again, but it'll take time and I don't have much hope it'd work.
(For some reason the save games for this scenario seem to be in a folder named "Scenario_ElNino_2" (and _3, etc.), while the Eden Burning is in a folder "Isabel Sarmento".)
Here's a link to the save game just before the scenario win: https://1drv.ms/u/s!AqHfqBwyVV-1rfwCAsmcFTIriZQqFQ?e=HIuDG0: (https://1drv.ms/u/s!AqHfqBwyVV-1rfwCAsmcFTIriZQqFQ?e=HIuDG0)
