Game Update Data Loss

Hello,
I was wondering if anyone has had a problem with the updates erasing data. I had a couple of engines and designs going, and got erased after the newest update. I was really quite shocked. I was also wondering if this can be recovered if enough people have noticed a loss in progress.

They have to be deleted because of the update, the changes from early cant carry over to new versions without breaking the game.

Don’t expect to keep anything until the game is actually done. Our team doesn’t have the capacity to drive game development forward and keep backwards compatibility without significantly slowing down development.
