So the union needs to do "original" selection, but one of his childs is
neverEndering.
That's never a good thing.

that's the caching PHASE one wrapping the child.

Hmm, why is this child neverEnding?
Is the entitySelector or valueSelector explicitly set to selectionOrder
RANDOM?
This would make no sense:
<changeMoveSelector>
<cacheType>PHASE</cacheType>
<valueSelector>
<selectionOrder>RANDOM</selectionOrder><!-- What's the point of
making it RANDOM if it's wrapped in a move cacheType PHASE? -->
...
</valueSelector>
</changeMoveSelector>
this would make more sense to shuffle on the phase level:
<changeMoveSelector>
<cacheType>PHASE</cacheType>
<selectionOrder>SHUFFLED</selectionOrder>
<valueSelector>
...
</valueSelector>
</changeMoveSelector>
