I didn't think to try this. The last resource was drinking water, and I could only carry three on one ship at a time. And I was afraid that the ship would be destroyed on the way. That's why I unload the gold at the tower.
By the way, I really like the animation of the light of the big lighthouse. I came up with a similar concept, but I didn't have time to draw it and put it in the game.
I will try the patched version as well!
