This is the second time I’ve come across this issue. After saving and closing down a Rhino project, I come back to open it and everything inside (all objects, all layers but 1, etc.) is gone.
I’m also looking for the autosaved versions of the project, but can’t find the versions browser that used to be under the File menu. Is this just a feature that has yet to be implemented, or can I find the autosaves somewhere else?
