Periodically, I will open an assembly, and a seemlingly random mix of components will be greyed out. When hovering over the file it says the file is missing. When I click and unsupress...Poof! There is the component in all its glory! Anyone else have this issue or know how to fix it? It's really annoying because I have to do this one by one!
I usally open each part in the assembly by right clicking on it in the tree and once all the parts that are messed up in assembly is open then close the assembly and click do not save and then reopen. Everything works fine after that. Save it after that and next time it wont have a problem.
