Geometries lost when reopened after crash

Hi everyone. I crashed my rhino earlier and when I reopened the previously saved file, some geometries were lost even though the layers are still there. The geometries that went missing don’t really follow any pattern (not necessarily the most recently added ones). When I try to recover from previous versions, despite the geometries showing up in preview, after the model is loaded, the same geometries are missing no matter how early I go in terms of date modified. Has anyone experienced this before?
