Shapes device glitch?

I was making another map, and I made a turret shape-thing it took me a while, but I place it down. After 5 hours, the shape turned back into a square? It still is the same color, but the shape reset. I checked my manage shapes, and they were all gone! I mean I am using a Chromebook however.

thanks fedora
