Need his with this Movement Script

https://app.roll20.net/forum/post/186018/script-mo...

So I followed his direction and I have it working, but after a few rounds it seems to break.
Some of the issue I am getting:

1) Some characters can't !DoubleMove
2) Some characters eventually can't move during their turn at all.

I am getting no error to share. Nor !ToggleMovement feels like it is working and !ResetPins ShowPins isnt working either

I don't know much about that script, or the system you're playing.

But here is something to consider:  Using the built-in in movement tracker might replace the need for a script.  If you 'grab' a token by clicking on it, then hit the space bar, you can track movement.  You can also place waypoints by hitting space once you start tracking.  And the DM can see how a player moved their token.

I am using this to prevent players from moving extra sneakingly, as well as locking their movement until it's their turn and in some maps - to give me a idea of their distance to have a trigger event occur.

Now I am not getting the errors above - currently it is letting me move freely, unlimited speed during the token turn only w/o any highlighting or leaving a pin behind.
