[AI] Problem with morphing ability in building order

[Ext3rmin4tor]

I have a custom race where there is a Spider Queen which can evolve with an ability based on the Destroyer Form of the Undead. The problem is that the AI seems not to know how to build the "evolution" of the queen. The AI should use the Evolution ability in order to evolve the queen, but it can't. Does anyone know how to do this?

This is the build order code fragment

function BuildPriorities takes nothing returns nothing
    local integer mine = TownWithMine()
    call SetBuildAll( BUILD_UNIT, 1, 'h01J', -1 )
    call SetBuildAll( BUILD_UNIT, 1, 'h01N', -1 )
    call SetBuildAll( BUILD_UNIT, 2, 'h01N', -1 )
    call SetBuildAll( BUILD_UNIT, 3, 'h01N', -1 )
    call SetBuildAll( BUILD_UNIT, 4, 'h01N', -1 )
    call SetBuildAll( BUILD_UNIT, 5, 'h01N', -1 )
    call SetBuildAll( BUILD_UNIT, 6, 'h01N', -1 )
    call SetBuildAll( BUILD_UNIT, 7, 'h01N', -1 )
    call SetBuildAll( BUILD_UNIT, 8, 'h01N', -1 )
    call SetBuildAll( BUILD_UNIT, 1, 'n01H', -1 )
    call SetBuildAll( BUILD_UNIT, 1, 'h01O', -1 )
    call SetBuildAll( BUILD_UNIT, 1, 'n02H', -1 )
    call SetBuildAll( BUILD_UNIT, 9, 'h01N', -1 )
    call SetBuildAll( BUILD_UNIT, 10, 'h01N', -1 )
    call SetBuildAll( BUILD_UNIT, 1, 'n01I', -1 )
    call SetBuildAll( BUILD_UNIT, 1, 'n01D', -1 )
    call SetBuildAll( BUILD_UNIT, 2, 'n01D', -1 )
    call SetBuildAll( BUILD_UNIT, 3, 'n01D', -1 )
endfunction

The Queen ID is n02H while the evolved ID is n01I.

I checked out the melee undead script for reference, and they use SetBuildUnit(1, BLK_SPHINX) to "evolve" a Destroyer from an Obsidian Statue, so I really don't understand why it doesn't work here.
