Occasionally, when exporting to DWG from Revit, some elements will be shifted in the resultant DWG as shown in the first image below; light fixtures moved out of the ceiling grids). While I do not know the reason for the shift, I have found it happens when exporting a Sheet with views. A workaround is to export the View directly, not from the sheet.
Here is the exported view (next image) with the light fixtures in the correct location...
If the sheet is needed in DWG format, then you will have to manually replace the bad drawing in AutoCAD. Not ideal, but it works.
