Unintended combined layers and clipping mask
Scenario:
- close a file that contains several layers
- open that file
- All layers have been collapsed into one layer, with all in a clip group.
- The clipping mask uses the arboard as the boundary. Even after releasing the clipping mask most of the art (but not all) outside the artboard has been deleted.
- The files I'm working with start life via 'Save As' directly to native AI file type from the SolidWorks drawing environment.
It's possible this is happening after 'freeze crashes' (Illustrator locks up and does not recover, must be killed in Task Manager) but I haven't noticed yet if there is a correlation.
This doesn't happen with every file, seems random.
As far as I know I'm not doing anything to cause this (the file configuration is as it should be when I close it), but please let me know if user-preventable or user-caused.
Obviously, if this is an actual issue, it would have to be 'red light' priority, as it blows away hours of work, across multiple files.
