I did it but the faces not change properly.
I change this:
["swadian_merchant", "Merchant of Praven", "{!}Prominent", tf_hero|tf_randomize_face, no_scene, reserved, fac_kingdom_4, [itm_dagger,itm_sword_two_handed_a,itm_courtly_outfit,itm_leather_boots], def_attrib|level(2), wp(20), knows_common, man_face_middle_1, mercenary_face_2],
For this:
["swadian_merchant", "Merchant of Praven", "{!}Prominent", tf_hero|tf_randomize_face, no_scene, reserved, fac_kingdom_4, [itm_dagger,itm_sword_two_handed_a,itm_courtly_outfit,itm_leather_boots], def_attrib|level(2), wp(20), knows_common, 0x0000000dc000210636db6db6db6db6db00000000001db6db0000000000000000, mercenary_face_2],
Maybe I'm doing something bad because It's the first time I edit module_troops.
