[0.0107] elevator fall

Description: if the robot or the girl fall in the elevator shaft while it's going down, the character is floating in the air at the end of the descent.



Steps to repruduce:
1. go to checkpoint 7
2. use the lever to get the elevator up
3. use the lever again to get it down
4. while it's going down, run and jump, aiming at the pole in the center

Result: physic glitches while falling & colliding with nothing at the bottom.

Fix in 0.011. I've put invisible wall instead. Not the most elegant way but it does the work. Thank you!
