I'm not sure, but I would check if there are differences depending on how you import the dwg.
For example:
Pen/color mapping at import of DWG/DXF files using the Keep Pen Index Number translator only works correctly using
Merge or
Xref. To Open or Drag-in (Place External Drawing) ignores the pen mapping table in the selected KPIN translator.
Autocad
Line type translation at import that has been enhanced in AC12 works correctly using the
Open or
Merge or
Drag(Place External Drawing) but not when you Xref.
The above means in brief that
only Merge works for me if I need a correct representation of the Autocad DWG drawing. I can't use Xref anymore which is frustrating. My layer tables get contaminated with the infinite amounts of layers that Autocad users like because of the ancient idiotic nowadays unneeded "Bylayer" constraint they still use.
There might be similar differences regarding text import. Please test and report back!
(Disclaimer: I haven't tested this with AC12 release 2285)
