Try rotate a wheel with Logic -> Trigger on Update and rotate the x.axis and the wheel goes to stop motion when countdown is done. By that i mean it looks like it has a variable 0 and tries to add like 10 but doesn't continue to add it, instead it seems to switch 0,10,0,10,0 you get the point.

I'm sure that's an issue that should not happen, since y.axis and z.axis are just doin fine.
