I just searched all my saved map downloads (needs a lot of time, when searching inside archives ).
Traktor.sco in was found in the downloads of the maps "Oberstedt -OMSI 2" and "CorumXL2".
Also I found the Traktor.sco in "Oberpfalz+3D+Splines-%26Objektbörse.rar" from 2016.
So the file may also be in the actual Oberpfalz Download (but I haven't checked it):
Wicked! I really appreciate you taking the time to look for me. Thanks ever so much!
