Hi Matt,

Yeah, that's clearly not desired behavior! What's happened, but I
don't quite know why, is that each halo is being given the same
particle as its maximum density location. Does parallel/serial change
this behavior? I'm guessing I can't diagnose this remotely, is your
dataset a reasonable size?
