When using popSolver, popkill dop is working to delete points. However, when using whitewater solver, popkill dop cannot delete points.

I knew another way: popGroup at first and delete (removepoint VEX) by pop Wrangle dop with that group, but I want to know why popkill dop does not work for whitewaterSolver/whitewaterObject dop. It's a bug in version 19.5.805?

from a quick glance at the internals of the node, without trying it indeed sounds like a bug

since postsolve feeds into ./kill/deathchance which overrides the death attribute using
therefore the following ./kill/blast that is deleting all particles where @dead=1 will only delete those and not the ones which originally had @dead=1 fropm your popkill

so I assume to quickly fix it try changing it to:
but also submit a BUG
