I HAVE A WORKAROUND SOLUTION
attila exe reset the file user.script.txt, this is the problem! now:
1- start normaly attila and uncheck al mod from standard MM and close it
2- start mitch MM and manage your mods
3- press launch and go away as usual but DO NOT press play on steam
4- set READONLY the file user.script.txt
5- now press play on steam and anjoy
6- after the gaming remove readonly setting from user.script.txt
for the next game session start from point 2
sorry for my inglish
