It's been a while but I believe the Creep sets a new State (i.e. “creeping”) that overrides normal collision and forces. I think you need to release the particles (via the State POP? not sure) for them to “carry on” being normal particles that can collide.

Thanks for the help, Peter.
Being new to Houdini, I must say that obscure behavior like the one exemplified above makes learning Houdini frustrating and above all time consuming at times. If it was for Peter's help, I would have never figured that out. The docs for the creep POP state: “This operator affects the following attributes: pstate (uniform scale)” and SLIDING is indeed a standard POP variable, but how am I to know that the creep POP changes the SLIDING state?

You know what. I've been using Houdini for years and yesterday I realized some important things about collision that I wasn't aware of. I think the collision needs to be improve and more example files with different collision case.
As soon as I finish figuring all this out I'm going to ask Side FX to do something about it.
Don't give up. Houdini is fun in the end.
