You have
Code:
DrawAfterParent = 1
AddGib = Gib
GibParticle = MOSRotating
CopyOf = Gib Pipe Small B
GibImpulseLimit = 2500
GibWoundLimit = 10
When it should be
Code:
DrawAfterParent = 1
AddGib = Gib
GibParticle = MOSRotating
CopyOf = Gib Pipe Small B
GibImpulseLimit = 2500
GibWoundLimit = 10
Note the tab for the "CopyOf" line
