There is no method "Has3DSkyInPVS"

[ts-co]

Tried calling a function like this: lua_run print(NikNaks.CurrentMap:IsRenderingSkyboxAtPosition(player.GetAll()[1]:GetPos()))

Received this error:

[NikNaks] lua/niknaks/modules/sh_bsp_module.lua:1066: attempt to call method 'Has3DSkyInPVS' (a nil value)
  1. IsRenderingSkyboxAtPosition - lua/niknaks/modules/sh_bsp_module.lua:1066
   2. unknown - lua_run:1

Couldn't seem to find that function in the GitHub repo either.
