Trainer sending out incorrect second Pokemon

Hi!

I'm using Pokeemerald with Pokemon expansion, Item Expansion and Battle Expansion.

I edited the grunt that stole Pico the Wingull and switched his team of 1 poochyena to read as follows in the trainer parties header:
static const struct TrainerMonItemCustomMoves sParty_GruntRusturfTunnel[] = {
{
.iv = 150,
.lvl = 15,
.species = SPECIES_SNEASEL,
.heldItem = ITEM_NEVER_MELT_ICE,
.moves = {MOVE_ICY_WIND, MOVE_FEINT_ATTACK, MOVE_QUICK_ATTACK, MOVE_NONE}

},
{
.iv = 150,
.lvl = 16,
.species = SPECIES_SANDILE,
.heldItem = ITEM_ORAN_BERRY,
.moves = {MOVE_BITE, MOVE_FIRE_FANG, MOVE_DIG, MOVE_NONE}

}
};
For his entry in trainers.h, I changed the items statement to read .items = {ITEM_SUPER_POTION},
I edited the ai to read .aiFlags = AI_SCRIPT_CHECK_BAD_MOVE | AI_SCRIPT_TRY_TO_FAINT | AI_SCRIPT_CHECK_VIABILITY,
I edited the line setting the party to .party = {.ItemCustomMoves = sParty_GruntRusturfTunnel},


In case I'm forgetting anything, the rest of his entry reads:
{
.partyFlags = 0,
.trainerClass = TRAINER_CLASS_TEAM_AQUA,
.encounterMusic_gender = TRAINER_ENCOUNTER_MUSIC_AQUA,
.trainerPic = TRAINER_PIC_AQUA_GRUNT_M,
.trainerName = _("GRUNT"),
.items = {ITEM_SUPER_POTION},
.doubleBattle = FALSE,
.aiFlags = AI_SCRIPT_CHECK_BAD_MOVE | AI_SCRIPT_TRY_TO_FAINT | AI_SCRIPT_CHECK_VIABILITY,
.partySize = ARRAY_COUNT(sParty_GruntRusturfTunnel),
.party = {.ItemCustomMoves = sParty_GruntRusturfTunnel},
},

Sneasel is sent out perfectly, but his second Pokemon is a level 75 Krabby.

I'm discouraged by this, because I suspect it has something to do with offsets and horrible things I'm accustomed to screwing with in binary hacking but thought I'd get to by and large ignore in decomp land.

Anyway, thanks for reading, hoping there's a trivial solution.

Figured it out! For any other n00bs, you have to edit PartyFlags in trainers.h. It is a bit mask, you can just look at other trainers that do this and copy what they do. Very simple.
