What happened?

Using SDMM on /tg/ code with tgstation/tgstation#84350 merged causes rendering issues when it comes to layers.

(I was also directed to post this here as a bug, I'm not a coderman so I don't understand whats going on)

Reproduction

1. Use SDMM on /tg/ code with aforementioned PR
2. Open any map
3. See images below

All the layers are on, but primarily turfs are visible. Areas are only visible on closed turfs.

Hiding turfs causes anything rendered underneath it to appear.
