Code:

turf
    wildgrass // tall grass
        icon = 'wildgrass.dmi'
        Enter(atom/A)
            if(ismob(A))
                var/mob/player/M = A

                if(M.dir == NORTH)
                    var/turf/T=new(locate(usr.x,usr.y+1,usr.z))
                    T.overlays.Add(/turf/wildgrass)
                    T.overlays.Add(/turf/wildgrassW)
                    spawn(6)
                        T.overlays.Remove(/turf/wildgrassW)
                        T.overlays.Add(/turf/wildgrass)
                else if(M.dir == SOUTH)
                    var/turf/T=new(locate(usr.x,usr.y-1,usr.z))
                    T.overlays.Add(/turf/wildgrass)
                    T.overlays.Add(/turf/wildgrassW)
                    spawn(6)
                        T.overlays.Remove(/turf/wildgrassW)
                        T.overlays.Add(/turf/wildgrass)
                else if(M.dir == EAST)
                    var/turf/T=new(locate(usr.x+1,usr.y,usr.z))
                    T.overlays.Add(/turf/wildgrass)
                    T.overlays.Add(/turf/wildgrassW)
                    spawn(6)
                        T.overlays.Remove(/turf/wildgrassW)
                else if(M.dir == WEST)
                    var/turf/T=new(locate(usr.x-1,usr.y,usr.z))
                    T.overlays.Add(/turf/wildgrass)
                    T.overlays.Add(/turf/wildgrassW)
                    spawn(6)
                        T.overlays.Remove(/turf/wildgrassW)
                        T.overlays.Add(/turf/wildgrass)

                if(prob(5))
                    M<<"Pokemon Battle! :O"
                return 1
            else
                return 0

Problem description:
Once I walk on the turf and the overlay is added, I can't get the overlay to go again once I try to walk on it again.

I know this is a really messy piece of code, but it's all I could come up with after being away from BYOND for so long.

Thanks in advance,
Vector2.

*edit*
I've also tried this with flicks, producing no luck at all. It simply deletes the turf under it.

Nevermind, I've fixed it. For those of you wondering, this is my new code.

turf
    wildgrass // tall grass
        icon = 'wildgrass.dmi'
        Enter(atom/A)
            if(ismob(A))
                var/mob/player/M = A
                var/turf/O = /turf/wildgrassW
                src.overlays.Add(O)
                spawn(6)
                    src.overlays.Remove(O)
                
                if(prob(6))
                    M<<"Pokemon Battle!"
                return 1
            else
                return
        New()
            ..()
            var/turf/O = /turf/wildgrassNull
            src.overlays.Add(O)



    wildgrassW // tall grass while being walked on
        icon = 'wildgrassW.dmi'
        is = "walk"
        layer = MOB_LAYER+1
        Enter(atom/A)
            if(ismob(A))
                var/mob/player/M = A
                return 1
            else
                return 0
    wildgrassNull
        icon = 'wildgrassW.dmi'
        layer = MOB_LAYER+1
