area fixes and catwalk placement

fixed a few areas by actually adding them into proper places and removed areas that were for some reason in Space (why would you do this), replaced catwalks ontop of space instead of whatever the fuck they were. control+click, people. it's not hard.

replaced air-filled plating outside of disposals with airless plating.

placed plating underneath some Security Lobby windows instead of regular flooring (whaddafuck), placed flooring in Warden Office instead of plating so the wires are covered up (why weren't they covered up), put pipes in a Xenobio pen in a slightly different area for the purpose of fitting in with other pipes, fixed a few more areas

shoved tinted windows into Security's washroom so there was some goddamn privacy, removed two reinforced windows in Engineering Lobby that seemed a bit silly to put down
