Possible Solution to "Map coordinate extents are too large" error

It is incredible that we are still finding ways completely break this engine. Last week, when working on my ill-fated microcontest entry, I encountered this strange error when attempting to load the map:
Host_EndGame: Map coordinate extents are too large!!
Check for errors!​

Checking Alt+P and the compile log for errors returned nothing, and the map itself was cordoned to a reasonable area. However, I was eventually able to trace the problem to an instance which had a cordon box of its own. Once I disabled this, the map loaded successfully.
Hopefully this helps someone who repeats this error in another twelve years.

This is because cordon actually fills the entire grid with brushes with the cordon texture (default skybox).

If an instance is somewhere other than the origin, those grid-sized brushes likely push over the grid of the main map and cause this error.

Oh wow I had a thread asking about this around a week ago and I couldn't find a solution to the error, and since im still a newbie to hammer I have no idea what any of that cordon stuff means. Do you mind explaining what that me kinda?
