Are you saving the file when it drops out?

Follow these steps:

1. Set all layers to be on/thawed/unlocked.
2. Use the WBLOCK command to export all data to a new DWG.
3. Import existing layouts. See: How to import a layout from one drawing file to another in AutoCAD products.
4. Purge and audit the file. See: Optimizing drawing files in AutoCAD with Purge, Audit & Recover.
5. Save the file.
