Karol Brzezinski proposed the following answer:
Hi,

I guess that when bodies are clumped you have to constrain the clump,
not the individual bodies. Your condition required material to be
Dolomite, however, only individual bodies has this property.

Try to change your loop starting in line 80 to:

for b in O.bodies:
    if b.isClump:
        b.state.blockedDOFs='zXY'
        b.state.angMom[2]=0
        b.state.angVel[2]=0
        b.state.vel[2]=0

Cheers,
Karol
