Oh yeah, if anyone else runs into the same "problem" I did (the game whining about the lack of cross path combat spells mod, even if you know you aren't lacking it), just rename CPCS.dm to CPCS0.8.dm. Because that's the newest one out, it ought to be the same.
Really weird that the official downloadables are called CPCS.dm while Llamaserver requires that very specific
different name for it.
