Hello, I'm trying to save player's origin before of he fell and "teleport" him to this origin if he receive fall damage. Since is there no specific way to do this, what I did then was loop through players each 0.1 seconds, save their origin and teleport they when receive fall damage.

It's working but sometimes the saved origin is the same point from where they fall, so when I teleport them, they stay falling infinitly. Also, I tried to save origin while they climb ladder, but if I teleport them to this origin, same problem happen.
