I am trying to create some old Pacific Coast League parks like Oakland Oaks park and I am having trouble expanding the size of the field with Oedit.  I unpack mfield0, mfield1, and mfield2 OK, then I edit the warning track in say mfield0, pack it back into the stadium.big file and it looks fine, but my changes don't seem to stick.  All 3 of these mfield files look the same to me.  Do I need to edit all 3?  Am I editing the wrong files?  I have searched for an answer but with no luck.  I appreciate any help you folks may give. 
 
Thanks!
