ISSUE:
Showing the purple/black checkers for surfaces, missing parts showing as dots, etc.
Tried deleting and reloading the missing library parts
Checked other projects shows the same issue.
Opened up same project on different computer - shows library parts.
My presumption is that the computer not showing the library objects is the culprit. But how does it get resolved, even though I've removed, and added back, the missing library parts?
