Yes, I second that.
There is a critical timestep for the integration, but depending on the
velocity magnitude of your particles, you might have to make the
timestep smaller, otherwise pathological effects like unstable
interactions (which can lead to leaking a particle through a facet)
might occur. Try decreasing it 2x or more and you will see if it makes a
difference. I was not sure if there were some particles going through,
since most or all are going through the top.
