[PC/XboxApp && Mac/Steam, old and up to date version] Unable to load saved custom map

Description: Loading a edited map (created via the humanking map editor) became to be impossible and crash the game every times.   

Attachments: Map-Forge-Your-Destiny.zip

Steps to Reproduce: 1.Create new map in the humanking map editor, 2.edit the map for hours (elevation, territories, climates...), 3. save the map with the save button 4. try to load the map in the map editor -> game crash & no more map 

Expected Behavior: The map should load and dont crash the game. => dont waste many hours of my life & and a part of my love for this game in the process.



I had this problem many times.
I swear this is the last time I've spent hours creating a map only to find myself crashing the game when I try to load it.

I've already tried creating different savegames etc... but that's just not sustainable.

Please can you solve this problem, which has been recurring since the first versions on Mac and currently on PC, or save me my backup
