Ugh! Grymforge REALLY doesn't like party of 6 mod. Game keeps crashing when I save or when trying to load saves. I am now saving like 3 times when I do save and praying they don't crash the game each time. Then when I load a save, I pray 1 of the 3 will actually load.
But, regardless, battles are still fine. I also like that my characters are still chatting and such. So still a better experience IF they made it legit.
