* Minor plane cube cleanup (#72038) ## About The Pull Request [Fixes area lighting not working on turf change in multiz cases](7b92deffbc) If you modify a area lit turf when using multiz, it'd end up using the wrong plane for its light, because of stupid shit on my part. Stupid shit resolved [Fixes some uses of plane masters that only specified one rather then all](a59ec96d29) We almost never only want to show SOME hidden planes. Should really make a helper for this someday * Minor plane cube cleanup Co-authored-by: LemonInTheDark <58055496+LemonInTheDark@users.noreply.github.com>
