We've heard from a handful of our Mac players that upgrading to OSX "El Capitan" may move or delete save files, rendering them unusable in the game.
We're currently investigating, and will post an update in the Technical Issues sub-forum when we know more.
Until then, please be aware that upgrading to El Capitan may affect your save file!
Thank you for your attention.

We're continuing to investigate this issue. It doesn't seem to be affecting all Mac users who have upgraded to El Capitan. Our testing so far suggests that lost saves *might* be recoverable. We'll post more information soon.
