Trap Movement Issue [Solved]

I want to make a trap moving to the direction I want by colliding with invisible arrows.
It works well for left and right directions, but the problem appears when I want to make it moving to left-down-right-up.
These are the event I’m using:

And the problem is?
Maybe your saw is in collision with two objects at the same time?
With permanent forces, you should probably use a Trigger once.

Nono, it’s not in touch with two objects at the same time. The strange thing is that it works now by reloading the whole project.
