- some custom hairs don't appear in saved projects; opacity is not an issue, just not visible. The "eye" is on in the scene tab.
-Selecting certain saved custom hairs in content manager causes an immediate crash (never did this before since update)
- Saving custom hair causes a file corruption to cause CC4 to not open (had to delete the corrupt ".hair" file to work).

I uninstalled and reinstalled CC4, but the issues still remain.
