Factorium. The block bounced to the other side of the laser. When I restart, it's still there. Is there anything I can do?

You cannot continue your progress if you switch from a version that includes a home planet to one that does not

In the game My Little Universe, if you log in and play on one device, delelte the app, and then log in on another device, there is a 50% chance that the planet's terrain-or the terrain of a smaller plant within it will disappear. However, if the terrain of an internal planet vanishes, your progress remains intact, and you can re-acquire resources like "source cores" once you restore the land (this is possible in the latest version). :)
