Hi I see the new update and i wanted to try, I press reset map and data, and don't erase the save, but I start again to the begin. Many hour lost i am so sad, I just wanted to know if I really lose my file or I can recover it and replayed on. Thanks. Sorry if my english is not perfect.

No no, lol , I want to play with my base i have made but with the map and missions reset. However, when I start the game with itch.io all my progress is loose I have nothing, I play like a beginner. But I can restart exactly where i was before the update, by pressing "Sand Alpha" in my folder.
