AutoSave not as good as 5.0 version

I think most people experienced this before. when rhino 5.0 crashed you will always find your last working file from autosave file. but from recently WIP experience. some time I can not get the file before wip crashed.
hopefully this could be fixed as good as the rhino 5.0 are.

is anyone experience the same?

Hi zhoushimiao - can you repeat this? (Use TestCrash to test it)
