Alembic not working in particle MESH REGION

So using advanced particle scenarios,

importing animated .ABC files dont seem to work with MESH regions of

pBounce
pKill
pAvoid
pFriction


but Shape3D does.

thats not very helpful of course when you need to slide rain down the front of a car

anyone can confirm please?

Is the topology changing?

Confirmed this in the release version of Fusion 8, as I posted elsewhere. I have a simple cube working, and Shape3D works, but anything more complex kills the particles beyond frame 250. Very weird. And a showstopper.
