[AI] Campaign AI how to set the different workers properly?

[Barade]

In my campaign AI I configure workers like that:

function ConfigureAI takes nothing returns nothing
    call SetTargetHeroes( true )
    call SetUnitsFlee( true )
    call SetHeroesFlee( true )
    call SetPeonsRepair( true )
    call SetHeroesBuyItems( true )
    call SetHeroesTakeItems( true )
    call SetSlowChopping( false )
    call SetWatchMegaTargets( true )
    call SetIgnoreInjured( false )
    call SetGroupsFlee( true )
    //call SetCaptainChanges ( true )
    call SetSmartArtillery ( true )
  
    call SetGoldPeons(8)
    call SetWoodPeons(5)
endfunction

However, I saw that in the thread which sets the actual workers for a campaign AI:

//============================================================================
function CampaignBasicsA takes nothing returns nothing
    local integer food_each = GetFoodMade(racial_farm)
    local integer on_wood

    call ClearHarvestAI()

    if CaptainInCombat(false) then
        set on_wood = 0 // WHY???????????????????
    else
        set on_wood = campaign_wood_peons
    endif

    call HarvestGold(0,campaign_gold_peons)
    call HarvestWood(0,on_wood)

    if harvest_town1 then
        call HarvestGold(1,campaign_gold_peons)
        call HarvestWood(1,on_wood)
    endif

    if harvest_town2 then
        call HarvestGold(2,campaign_gold_peons)
        call HarvestWood(2,on_wood)
    endif

    if harvest_town3 then
        call HarvestGold(3,campaign_gold_peons)
        call HarvestWood(3,on_wood)
    endif

    if do_campaign_farms and FoodUsed()+food_each-1 > food_each*(TownCount(racial_farm)+1) then
        call StartUnit(TownCount(racial_farm)+1,racial_farm,-1)
    endif

    if build_campaign_attackers then
        call BuildAttackers()
    endif

    if not CaptainInCombat(false) then
        call BuildDefenders()
    endif

    call FillGuardPosts()
    call ReturnGuardPosts()
endfunction

It always resets the wood workers to 0 when the captain is in combat?! Why does this happen? Is it done for Ghouls of UD?! I am not even sure who the captain is when my AI attacks (their hero?!). I do not specify any captain in my attack waves:

call InitAssaultGroup()
    call CampaignAttackerEx( 2, 3, 3, DEMON_OVERLORD )
    call CampaignAttackerEx( 0, 1, 2, DEMON_FEL_STALKER )
    call PurchaseZeppelin()
    call AttackWithMount()
    call CampaignAttacker( 0, 1, hero_id )
    call Sleep( M3 ) // Waits 3 minutes before attacking
    call LaunchAttack()

Will it be the hero and why should the wood harversters be 0 then?! How can I prevent it? The AI needs more wood.[/CODE]
