Although the player character is now on Nauvis, the rectangle is on Fulgora. It's not very hard to find it, it's on the large main island.
I was doing some copy/paste/blueprint work and possibly may have pressed some exotic combination of keys. The rectangle persists through saves and loads, respects shadows from other buildings and doesn't go away when building over it. Nothing in the common graphical glitches seem to make a difference, which I wouldn't expect either since the object persists in the savefile the bug must be logical.
I have attached the log files I have, but unfortunately I don't think any of them are relevant because I tried to load and reload a few times (as well as exiting the game) before I got this far.
I would be happy if there was a way to remove it just from my save, but all in all it doesn't bother me much.

[2.0.23] Persistent blue rectangle drawn on terrain
Re: [2.0.23] Persistent blue rectangle drawn on terrain
Hello, thanks for the report.
Not a Factorio bug. The rectangle is created by assemblyanalyst mod, so if it is not supposed to be there, it's bug in that mod.

Thanks, that makes sense.
