Making siren head's path finding was a nightmare

I thought with a consistent layout his path finding would be straight forward but it was a nightmare.

He would face the wrong despite facing the right way on the Z-axis, he would get stuck on corners despite adding momentum and increasing the cell agent radius for the nav mesh, sometimes siren head would just throw itself into the ground, and more.

A couple problems were fixed from help by the community, some never got responded to, so 70% of it's path finding is held together with hopes and dreams.
