I'd go ahead and update, but keep a copy of the library as is now somewhere in case you need it. Try the 11 migration doors and windows, some problems, but better.
The problem I reported with missing CW was operator error
. I didn't realize that the person working on the site was using a file that did not have the same number of stories as the main file.
What I found interesting was that all elements were there, but if you place a hotlink, only the elements assigned to visible stories showed. When I merged, it added the stories so that is why I and person #3 didn't catch on to what was happening. Our excuse anyway.
Placing the hotlink, all we had to do was add the missing stories with their correct heights to match the building file and all of the building was revealed. Pretty neat actually.
