A housekeeping note for those of you upgrading to BHaH2. Careers appear to be fully transferable using Robert Wiggins' "User Files Backup Utility."

edit - Additional housekeeping note: using the old WOFFkeys.xca file backed up by the utility prevented access to the new Lewis gun lower, raise and reload commands. When I removed that from Appdata/Roaming/OBD_Games/OBDWW1 Over Flanders Fields folder and restarted the game, the game engine regenerated a fresh WOFFKeys.xca file and I could now see the new options in workshop key commands. Now I gotta reconfigure my controllers. Oh well.
