I have spent considerable time editing line feature classes in one of my file geodatabases in an ArcMap 10.2 map file. Today, I returned to it, opening the map file, and none of the layers appeared in the contents panel (list by drawing order). I checked out the contents tabs -- nothing shows in 'list by source', but I can finally see my database objects in 'list by visibility' and 'list by selection.' I can't open their properties, attribute tables, etc. I could still see the edits that I made there, too, so that's good at least.
Switching to layout view, nothing was there. Back to data view. Still there. Layout view, nothing. I tried toggling drafting mode. No good. Coordinates? Should be there.
I decided to move right ahead with topology to make sure my lines were all lined up properly so I could convert my lines to polygons. I enter edit mode, say I want to edit my geologic lines (weird that it shows up there, but not in the contents), open up my topology feature, select the features I want to check, and I can't open the error inspector.
Fine, so something's off and it looks like I can't just ignore it. I'm used to Arc throwing errors.
I opened ArcCatalog and opened my map document through that. Everything shows up fine in contents, etc but all of the work I did the other day is GONE!
I close all of Arc and open up the map document directly like I did earlier. My edits are there, but I have the same problems as before. I load my old line featureclass into the map document. It only shows up in the contents. I switch to layout view, and I can see the lines. But wait... where are my edits!? Switch back to data view. Ok, there they are. Back to layout view. Edits not there anymore.
I realize that I'm rambling, but I'm not quite sure how to communicate this issue. How do I recover my edits? They've clearly been saved somewhere, but not in the file geodatabase where they should have been saved... or are they? I can't check the layer properties to make sure that the data source is correct, and I'm more than half-convinced that what I see is only a "ghost" of my data, but really don't want to spend another day drawing all of those lines again.
