Ladders problem (character keeps on falling down)

[Bbotone]

A LITTLE MORE ABOUT THIS PROBLEM

using this cavebot script for carlin theater, I noticed that it doesnt simply wrongly goes back to the previous waypoint, but goes to the waypoint closest of the sqm your character is standing in, just like it does when you mark cavebot as active. This scripts is just going through floors -1 0 +1 0 -1 0 +1 0 -1 0 +1, when it reaches the second -1, going up to 0, and keep falling down, it goes to the first 0.
