Collision on spiral staircase.

As the title states, the spiral staircase does not flow smoothly. The character model gets stuck on the spiral from 1st floor to 2nd, etc. The anchor points are difficult to align properly as well. Maybe code it as a foundation that can snap onto itself and auto-align to keep the spiral smooth. Maybe take out the small landing square for 2nd floor and up unless a floor/ceiling tile is available.
