Level Design Invisible mesh

[atlantian.wizard]

I was creating a new map using the sdk and everything was going fine until all of my static meshes simultaneously turned invisible. I don't know what i clicked to make it happen but I can't even restart the sdk with a new fresh map as the bug persists.

anyone know how to fix this?
