I was able to solve the problem-In the _save.lua file I put the colors of all the armies on 0. This helped and the map opened.
It is possible that the program could not find the color for some armies before the fixes, because the color number for some armies might not be occupied.

I tried to create a campaign in FAF Map Editor, but I encountered a problem - I can't control cameras normally in FAF Map Editor. I tried installing the SupCom Map Editor by following the instructions on the FAF Wiki. I open my map using the SupCom Map Editor, and after a few seconds the SupCom Map Editor crashes.
I can't control cameras normally in FAF Map Editor, and i need to open my map in SupCom Map Editor to edit the cameras normally.
Please help me open this map using the SupCom Map Editor.

P.S.: Sorry for my bad English - I'm from Russia and I translated through the translator program.
