Ni No Kuni AoB experience multiplier freezes system, and inf HP makes bosses unkillable

[msherga]

Whether run once or constant, and no matter the multiplier, the game freezes when Artemis is attached and wrote. No Webman, only mmCM. Running on a CECHA01.
Other cheats work just fine: item multiplier on gain, infinite item usage, infinite HP/MP etc.

Also, when using inf HP, every attack on a boss registers as a miss.
