I have popforce network attached inside rbd bullet solver. The pop force is animated to only trigger at certain points during the timeline. While caching rbd solver, it gets stuck at around when popforce is being triggered. And each frame then takes an hour to cache. Cache gets stuck at "Finding Contact Points". What can I do about this?

I have 2000 points instanced with a geometry which is 12k prims. Cache has no problem saving when the 2000 geos are colliding with ground surface and each other.
