So while I was working on a project suddenly I got a .sch files extension in folder.
I searched for files with offline process applied but I don’t have any.
So I select everything and apply the “make offline process permanent” and the “flatten realtime process”, this usually works.
But this time nothing happens as there isn’t any applied.
so I save it and still have the csh files.
Getting crazy over this so I delete all channels leaving an empty project and save.
csh files still there… 
any ideas?
