Map Editor Bug/ Map cannot be cloned

Expected behavior
When I try to load the map it loads to
6/7 Progress and an error code line appears.

Steps to reproduce the behavior:

I tried to load the map on 4 different browsers.
This error occurred after properly deleting a border -clearing the background and then saving. (The last border to finish the map)

Information:
Browser: All Browsers

OS: Windows

Any other relevant information: The map is saved under not cloneable - Is it possible for an admin/mod to change this so I can salvage the map by cloning?

Attachments: eh- i think this explains it well enough.

I have the same problem with the "Star Trek War" map
I also tried on different browsers and different computers even after resetting the cache, always with incognito mode

For my "Star Trek War" map that has this error at point 6/7 of loading and does not allow editing, could I ask if it is possible to recover it?

The problem certainly depends on the borders, I was making the map, if to recover it you have to eliminate all the borders that's fine, I could redo them, but redoing it from scratch with nations, cities and units is a bit too much...
