Annoying Fabric JavaScript Bug

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

I use a mac to play, using safari and chrome. sometimes i play a map or a scenario, a bug like this will pop up.
this bug also occurs when you made a map, you re-edit it a few times, then this bug also has a chance of occurring.

I tried to read into it, but i know little about javascript.

This is because HTML 5 AtWar uses FabricJS 1.5.0, which requires paths to be not empty. Obviously I don't know how the Amok/Clovis wrote the code, but it is a known error in 1.5.0 that complex SVGs with potentially empty paths cannot be rendered.

How do i fix it?? i have the same issue

Try switching to a browser that's user friendly. Like fire fox.

Got through turn 1 and 2 in this game:

Now I got stuck at the loading screen with battle resolution turn 3 and was unable to click anything. It just keeps loading and displays a fabric js error and hangs at 7/7. Tried 2 different computers. Tried Multiple browsers on each. Cleaned temp files and cache on firefox and used ccleaner as well. No luck. Any idea what is going on?
