Buying treasure can u spend multiple goods?
When using a good for upgrade and it's in a warehouse what region are they talking about, can you just use it as if it's on the ship that's being upgraded.
In the prologue the only warehouse you have is in your home province. As long as your ship is in the same place, then yes you can use it as if it were on the ship.
Do both upgrades and structures go away after a single game?
