Optimize scene deleting MASH netowrk

[seandunderdaleBAKA7]

Ive run "optimize scene" on a file Ive been working on, and continued to make lots of changes. Then I found out it deleted my MASH network. I tested this on a new scene and it does indeed delete a working MASH network. I also found that I cant import said MASH network from a previous file so Im left having to redo all my work.

Is there a workaround for this?

Hi i also had this issue, luckily I have a back up. but what i wanted to do is clean the scene of unused mash nodes that are not in use. Is there a Good way to clean up mash nodes that are no longer connected to a network?
