As the title says - custom ai parameter option will not always work. To be fair it partially works. It may work for 2-3 times - after i re-launch the game -, but after the 3rd or 4th time i launch rf2 it seems to be deactivated again. I am sure there are more little things like that, that need to be assigned. I really hope that someday all these would lie in the past, cause this game has really potential..
