There seems to be some layers missing in this x-ref drawing. I can still see how it originally looked like in the thumbnail in the Recent Documents column (entitled "x-site"), but when I open it up, there is a lot of stuff missing.
I've verified that all the layers are turned on. The last thing I remember doing before all the stuff disappeared is writing the drawing as a block so that I could import/insert it into another drawing. Why is all this content missing and how do I get them back? I've attached a screenshot of the thumbnail that shows how the drawing originally looked like vs. how it looks like whenever I open it up.
