I get some nice results with the Pyro Sop Solver in H19, but my simulation gets slower and slower even though my cache file size decreases, then crashes at some point (sometimes sooner, sometimes later). Is it possible to save cachepoints and resume the sim from them or do I have to go back to dops for that? I'm on Houdini 19.0.498.

I moved the sim into dops and get similar results without the slow down and crashes. It feels like the sop pyro solver is recalculating each frame from the start frame. Is this a know issue? Maybe just with my build?
