requirebuffontrigger is wierd with targetcorpse spells

OK, so this:

Code:

<spell name="Disintegrate Corpse" type="targetcorpse">
<effect type="damage" conflagratory="6" />
<anim sprite="sprites/sfx/disintegration_hit/disintegration_hit" frames="6" framerate="80" sfx="flame_weak"
centerEffect="0"/>
</spell>

<spell name="Stay Destroyed Forever!" type="adjacent">
 <effect type="trigger" amount="1" spell="Disintegrate Corpse"/> 
<anim sprite="sprites/sfx/null" frames="1" firstframe="0" framerate="120" sfx="blast" />
 </spell>

Totally annhilates the corpses of the creatures it hits.


But THIS:

Code:

<spell name="Disintegrate Corpse" type="targetcorpse">
<effect type="damage" conflagratory="6" />
<anim sprite="sprites/sfx/disintegration_hit/disintegration_hit" frames="6" framerate="80" sfx="flame_weak" 

centerEffect="0"/>
</spell>

<spell name="Stay Destroyed Forever!" type="adjacent">
 <effect type="trigger" amount="1" spell="Disintegrate Corpse" requirebuffontrigger="1"
requirebuffontriggername="Hyperrotational Peck of the Flightless Overlord" />
<anim sprite="sprites/sfx/null" frames="1" firstframe="0" framerate="120" sfx="blast" />
 </spell>

Totally doesn't, even when you have the relevant buff. The only difference is the requirebuffontrigger, which leads me to believe that it's borking up some obscure aspect of target-passing or some such thing like that.
