72Keizer A3a

Update for minor errors, e.g. overlays with no assigned faces and sloppy displacements.

Changelog for alpha 3:

Point A:
-Added new stairs into building overlooking the point to give BLU easier acces
-Redid right side flank to make it more advantageous for BLU and more interesting in general

Point B:
-It's completely redone lmao (The old B did not feel interesting to me; it did not have anything unique or special.)

Changelog for alpha 2:
-New approach to A for BLU. should hopefully make it less of a walk of death
-New high ground at B for RED
-general optimization
