Well, looking at the "disable RR commands" it appears that while it does disable RR, it also disables all/almost all your heavy cavalry.
The "disable RR command", according to the scripts file, sets the trigger "event_counter HEAVY_MAIL_ARMOR 1", whereas the "export_descr_buildings" has the entry for "norman cavalry" (the version which has a pool that tops out at "1" and not "0.1") listing the condition "NOT event_counter HEAVY_MAIL_ARMOR 1". Their are several other units this affects.
Likewise, it sets "event_counter FULL_PLATE_ARMOR 1". And with this, the feudal knights all disappear, as they require "HEAVY_MAIL_ARMOUR 1" but NOT "FULL_PLATE_ARMOUR 1"
The unit is their under RR, but not their when RR is disabled. This strikes me as a bug.
