This wont be helping:

dummy2: Breaking dependancy loop at dummy1

dummy1: Breaking dependancy loop at dummy2
You really don't want to create colocation loops, they'll cause the
cluster to behave somewhat erratically (as you're seeing).
I removed the following constraint and the resources stopped moving:
<rsc_colocation id="location2" rsc="dummy2" with-rsc="dummy1"
score="-INFINITY"/>
