Map Editor stuck on loading

I've spent a while working on this new map based on The Expanse, but I can no longer make any edits or open the map. It's stuck on 6/7 loading map. Is there any way to salvage this? I bought premium just to work on it.

No because AtWar runs FabricJS 1.5.0, AND WHOEVER WROTE THE CODE SHOULD UPDATE FABRICJS TO THE NEWEST VERSION OR NOT HAVE SUCH COMPLEX MAPS BUT BECAUSE WE NEED THESE COMPLEX MAPS WHY DON'T YOU JUST UPDATE FABRICJS GODDAMNIT

Puff for new admin

I also have this problem. Neither map editor works. I'm not sure if theyr'e still being developed.
