Trouble putting Alexander units into RTW

[Elmo J Muppet]

Hi everyone,
I'm making a new team in RTW, and have copied info (from export_descr_unit, descr_model_battle etc) from Alexander to the main Rome file. For some reason these units now only work if I give them the mercenary_unit description in export_descr_unit. If I leave this out I get a CTD at the battle load screen.
I've checked all the usual stuff - making sure they're available to the right faction etc. I've added units from Barbarian Invasion and these have worked fine without having to be described as mercenary_unit, but for some reason the ones from Alexander do. This seems pretty strange to me, as some of the units I'm adding aren't even mercenaries in Alexander. It isn't a problem for single battles but means you can't build them in the campaign. Can anyone help me out, please?
Thanks.

Did you give the right factions their own textures and sprites in DMB yet?

[Elmo J Muppet]

I certainly think so. Here's an example of what I've got in DMB and EDU;

EDU:

type perg_citizen_pikemen
dictionary perg_citizen_pikemen ; Citizen Pikemen
category infantry
class spearmen
voice_type Light_1
soldier perg_citizen_pikemen, 60, 0, 1
attributes sea_faring, hide_forest, can_sap, mercenary_unit
formation 1, 1, 2, 2, 8, square, phalanx
stat_health 1, 0
stat_pri 6, 2, no, 0, 0, melee, blade, piercing, spear, 25 ,1
stat_pri_attr spear, long_pike, spear_bonus_8
stat_sec 3, 1, no, 0, 0, melee, simple, piercing, sword, 25 ,1
stat_sec_attr no
stat_pri_armour 6, 3, 2, leather
stat_sec_armour 0, 0, flesh
stat_heat 1
stat_ground 2, 0, 0, 0
stat_mental 2, normal, highly_trained
stat_charge_dist 30
stat_fire_delay 0
stat_food 60, 300
stat_cost 1, 440, 200, 50, 75, 440
ownership romans_scipii

DMB:

type perg_citizen_pikemen
skeleton fs_slow_spearman, fs_slow_swordsman
indiv_range 40
texture romans_scipii, alexander/data/models_unit/textures/ALEX_phalangist_macedon.tga
model_flexi_m alexander/data/models_unit/ALEX_phalangist_lod_1.cas, 15
model_flexi_m alexander/data/models_unit/ALEX_phalangist_lod_2.cas, 30
model_flexi alexander/data/models_unit/ALEX_phalangist_lod_3.cas, 40
model_flexi alexander/data/models_unit/ALEX_phalangist_lod_4.cas, max
model_sprite romans_scipii, 60.0, alexander/data/sprites/macedon_ALEX_phalangists_sprite.spr
model_tri 400, 0.5f, 0.5f, 0.5f

This all works fine if I keep the mercenary_unit description in EDU, but I don't really want to. I don't think I've missed anything.

Try disabling the sprite line, or making new sprites with the RTW engine. For some reason Alex sprites often don't work with the RTW engine.

[Elmo J Muppet]

Brilliant! I took out the sprite line and it's working now. Thanks.

I wonder why it mattered whether the unit was mercenary or not when I left the line in though. Doesn't seem to make much sense. Oh well.
