Hi!
I was playing the game and got to the second island, after a little while it was time to move and I moved the nichelings to the travel ports and clicked on travel. The screen then cut to the middle of the sea and no island or nichelings anywhere, I tried everything, zooming in/out, rotating, moving etc. but nothing worked so I tried to turn the day. When I turned the day a pop-up came up saying my species had gone extinct.
Have an awesome day!
