acabo de comprar la isla de lava a 25 gemas toda la isla y tan solo se me compro una sola parte de la isla

@Paolo-Quezada The gems are to unlock the island. Once you did that you have to buy expansions with gold. Make sure to have enough neighbors.

@Paolo-Quezada This is not a bug. You have to purchase each island AND each island has 9 expansions that must be purchased separately. It has been a very long time and prices have changed. Generally you have to spend gems to purchase the islands and then gold for each of the 9 expansions.

I believe I believe that all expansions have to be purchased before you can move to the next island as well.
