There's pretty much zero visibility to holes in the floor leading to other Z levels

There is a hole in this hallway. I watched 3+ people fall into it crashing through to the deck below.

Can you guess where it is? Every single tile in this 3 wide hallway west of the moth is safe, except for one.

Hints:

Spoiler:

Its not a tile with any purple lines.

Spoiler:

There are no items on the tile.

Spoiler:

It is none of the tiles on the bottom row

Do you have parallax disabled?

[TheFinalPotato]

You have multiz parallax disabled in your preferences, so the normal visual cues that would apply here aren't.
Need to re-examine if it actually impacts performance because if not it's just a bait pref that shouldn't exist.

I’m forever skill issued. But yes I did turn it off in hopes of better performance

epic fail

[TheFinalPotato]

I don't think it... does anything, so there is an issue here it's just not the one you thought
