When opening up a solo file there is an option to repair it, yet opening a teamwork file there is no repair option. The architect I am working with said that the best he found out was that he had to safe as a solo file and reopen it. I wonder if there is another way.
That's the way I've always done it. "Take it down" from the BIMCloud, Open the PLN with a Fix, and while you're at it, try to relink Libraries, find missing parts, purge the Embedded Library, purge extra Attributes, repair Hotlinks and External Drawing links, and check for missing filters in Views. If you find a lot, close it and re-Fix it. Delete or re-name the old Teamwork file, and Re-share. It can sometimes work wonders, but not always.
