I have been working on a map for a while now and for some odd reason, My hammer crashes and when I re-open hammer, all of my entitys are gone. In my "Entity Report" all of my entitys are there but the names are blank. All of my funcdetail brushes are entitys but the type isnt Funcdetails, they are blank. I can replace the entitys but its happened before. I wasnt too far in the map so I just started over. But this is to much of my time to start again.
