[Update]Fixing the bugs related to obtaining gold

There is a feature named "Gold Ores" where you can build a "Gold Mine" and "Bank" to produce gold. But unfortunately there was a game-breaking bug that doesn't generate any "Gold Ores" when the game tries to create a map. I have fixed it and updated the game.

PS: This was my submission for GWJ#53 but I have to leave the jam because of the game-breaking bug :((( so I want to work on this game more. I'd really appreciate if you leave a feedback or an idea to improve the game.
