I did it, I survive the zombies infested island. I survive the android and Cthulhu's monsters and madness! I build a largest boat and then I don't have enough people to operate then a slave trader arrive clearing zombies for me. We quickly buy more people and gather many thing including few animal boomgiantrat and thrumbo then we load ton of stuff into the ship and plan for escape out of this madness island. then after the boat fully load up and some people fall to sleep of exhausted. I quickly command people to get up and let them free to move again. They move into the ship but they not leave! they stay there for whole day until few zombie start to notice our long gate to the sea.
but in the end

We sail to the sea. We did it
As epic music from few of music mods were playing. I told my people on world map to forget about that island

The message pop up and say
Everyone died
(same message as you lost everyone)

I was fear but I check that I still able to control my people but my 2 boomgiantrat are not on the boat and we still only half way across the world

Was everyone really dead? Will I able to play the save again? Will developer look into this bug?
