We have created Five Worlds now and made significant progress in each just to have them crash and become corrupted.
My Wife and I have decided to go back to the other more stable Block Game, and will be deleting this one.
Don't get me wrong, this Game is very fun, challenging and rewarding, but there is nothing more punishing and frustrating then watching your time and effort go down the Drain.
Yes, we have been using a few Mods.
Better Ruins, Yabba Forge, and Anvil Metal Recovery+.
