After losing a build that took 3 whole hours to work on to not saving. I have an idea for the game. Backup saves.
Here is the idea
Every single time, or like every 5 minutes, something changes in the designer, a backup save is made. A backup save is like an auto save. But let’s say, You are working on a build and you pull a different plane up from your saves, and you exit the tab (I’m on mobile btw so this example is on mobile) you forgot to save your work, you can go to the backup saves and pull it back up and save it, and not needing to restart hours, or days of work.
