In switch tower, after elevator, sent robot to push block through the wall.
When I switched back to the girl and climbed the stairs, I was unable to jump... then I discovered the girl was no longer detecting the floor under her and simply remained at her last height (the top of the stairs in the switch, stairs, pillar room at the center of the tower).
game runs normally, am still able to switch between girl and robot, and all of robot's actions behave normally (can walk up and down stairs and jump).
