Hi, Right now, Chrono::GPU does not checkpoint meshes or boundaries for a set of reasons. But since you know the position of your mesh from querying the Chrono bodies, you can restart the simulation using that information.
For the mesh flipping issue, I can hardly believe a 600g object that is several centimeters' wide has a moment of inertia of around 0.1 g·cm².
