Bug: I can't edit my map

Hey guys. I was trying the HTML5 map editor and building some stuff, but suddenly it started to not open anymore. After a little problem with seeing the thumbnail of a country after uploading it, I decided to save the map, quit and reopen it (I did it periodicaly just to be sure everything I put was really saved), but then came the problem. Now, everytime I open it, the map only loads until the 6th step (6/7 loading map) and then stops. Also, the following message appears on the chat when the 6th step begins:

Σημείωση:

Error: Uncaught Error: 'path' argument is required, Script: https://pt.atwar-game.com/java/fabric/fabric.min.js, Line: 523 Column: 192, StackTrace: Error: 'path' argument is required

PrintScreen:



I also opened the Chrome Developer Tools and it showed some errors in the page. I don't know exactly what each stuff means, but maybe it can help you, so here are the prints.









The "<img>" item keeps repeating itself constantly.

All my other maps are opening normally and I can even create new ones, so I guess the problem is with this one. I already tryed to clean the browser cache and cookies, but it didn't work. I also tryed changing the browser and opening the map with Firefox, but didn't work too.

What is happening?

Is there any way to solve it?
