Do you mean you're turning the option off whilst your units are still physically moving? If so, don't do that. Turn it on, move your units around, turn it off along with all the other options before a battle or before you end your turn.
If you mean you're turning it off and on again during a turn, and it's not working, then I don't know what's going on there. It's working fine for me.
Well the game is still pretty bugged and unstable. that might be the cause of the problem, can't say though.. But everything working fine on my part. Except i have to use "/" when entering a battle, ending a turn or making a decision. small things
