3D test dummy keeps disobeying simple go here command automatically

Godot version4.0

Question

On my 3D test bed for a game I encountered a path finding error, I tried to have my test dummy go up a ramp (he almost made it and when I refined the code he seemed to dtop halfway up (which was less) so I put the target on a flat surface on the high point and moved the target to a couple of meters ahead to find out what went wrong. That failed as he kept missing the target after altering the code he had a quirk of just going the opposite way running of the maps edge (If its any help I'm testing for modular 3D level structures for a xcom type game, and was planning to have a modular map that could be reused)
