Sorry, it's in a subfolder. Look in the campaigns\CampaignData\Default folder.
BB, are you sure WOFF reads and uses data from this file (location)? I tried to delete it (for testing purposes) and WOFF have not complained and run campaign mission as usually.
I suppose we should edit/modify simulation.xml file located at "xx:\OBDSoftware\WOFF\OBDWW1 Over Flanders Fields" folder. File located at Default folder is old, obsolete version, incompatible with current version of WOFF UE.
BTW, this version allowed to fly FE2b in fighter role, enabling following attributes:
permitFightersWithoutFixedGunsToFly="y"
permitFightersWithoutFixedGunsToFight="y"
That option is unfortunately not available anymore and FE2bs can be used as moving targets only
