[Missing Savefiles or "rollback" On restart - Got a workaround]

Thank you! This solved my problems with saving.

Seems a silly thing to have happen on a console with tons of free memory, but at least now I know to keep old designs and flights to a minimum to avoid this problem for now.

[Why is this game still on the market place?]

I bought it a couple of days ago on XB1. I'be never played it before.

I'm seriously addicted. Yeah, there's a couple bugs that annoy me (losing the ability to set maneuvers and having to save and reboot the game is the biggest one). But I have never played it before, so have no expectations. 

As a big Minecraft player on PC frustrated by the limitations of the XB1 version, I know where you're coming from, but remember that expectations for new vs. experienced players is vastly different.

Since this game is on the Marketplace, the community found at least one new fan not too fussed by the problems and expecting patches to improve things. Not so bad.
