I am having problems with linking a structural file. There are old walls that keep appearing in our revit model that were removed from the structure file months ago, but keep showing up. I have removed the link and reloaded it from a completely new file, and the problem keeps happening. I have checked the structure file, turning on all worksets, object types, and phases, and the walls aren't there. This is a huge problem from our end because it means that we cannot easily check the structure file against our floor plans and means that we don't know what to actually trust in the structure file as being up-to-date.
