This is by far the best working version, when I consult archives of tests made by vonkaja
This is the 6 July version

Some defines that I changed

NDefines.NAI.FALLBACK_LOSING_FACTOR = 0.2 -- The lower this number the longer the AI will hold the line before sending them to the fallback line
NDefines.NAI.PLAN_MIN_SIZE_FOR_FALLBACK = 100 -- A country with less provinces than this will not draw fallback plans but rather station their troops along the front

NDefines.NAI.MANPOWER_RATIO_CAREFULNESS_THRESHOLD = 0.2 -- if manpower ratio (available/used-by-army) is less than this, start being more careful with plan execution (i.e. don't throw your men into the meat grinder if you're running out of manpower)
