## About The Pull Request Vents/scrubbers look a bit weird as their pipes still go above catwalks/glass floors but I need my stuff from #89702 and it should be atomized from this PR. Closes #87022 Closes #88823 ## Changelog 🆑 fix: Fixed spiderwebs, alien weeds, kudzu, and other stuff layering below catwalks and glass floors /🆑
