Free bridge doesn't appear on start

[nic0lette]

Even though the bridge flag is set when the game starts, it doesn't appear until the player leaves the overworld (to go into a dungeon, a city, or even just saves, quits, and reloads).

This happens because items/flags are set by the world map loading script, but that happens after the map is loaded, so it would need to be reloaded to work.

I think the only way to fix it is to either:

• Leave/reload the world map in the middle of the map loading script (not super obvious how to work with this at the moment)
• Have the flag set some other way when starting a new game
• Edit the world map itself?
