Debug error: Z-Level view violation

[ChucklesTheBeard]

Describe the bug

"Z-Level view violation: the flying polyp tried to attack the fungaloid.", monster.cpp#L1593

Steps to reproduce

1. Load save.
2. Wait a turn.

Expected behavior

No error message.
Presumably flying monsters shouldn't try to attack across Z levels when 3d view is disabled?

Screenshots

3d vision is disabled:

The polyp and funagloid in question are west, one building over. They both presumably spawned from the portal on the internet cafe roof.

I can confirm this is happening. I saw it happen with hallucinations while performing long actions like sleeping or cutting down trees.
