Missing instance in assembly file

I have a assembly model that is failing when I open it. I says that a model is missing. An instance of a family table was obsoleted, but I do not see where in the assembly that the missing part is suppose to be. When I go back into the family table, and temporarily add the instance it is looking for, the assembly model is "happy" but I still do not see where the model it was looking for is supposed to be. Here is the tree and model info screen shots both before and after adding the missing instance back into the family table. Again, I do not see where the part is suppose to be. Is there a way that it could have been hidden?

Assembly before the missing instance was recreatedAssembly after the missing instance was recreated

I renamed the file before trying this.

I decided to delete the front plane (lower in the tree and can be recreated from the right and top plane).

I suspended all of the items except the missing item.

After recreating the front plane, I was able to reattached any constraints that were looking for the front plane.

Every thing is now happy with the structure.

Try looking at the reference viewer. Sometimes it shows broken links or missing information that you can't find elsewhere.

Before or after "recreating" the missing instance.

Good question.

I would have to say try whichever you have open first and see if it shows anything. Then try the other.

I would expect it show better without.

Is it in one of the groups?

There is always more to learn.

It is not in one of the groups nor in any of the subassemblies. I expanded everything all the way just to check.
