Thank you! We are aware of this bug (shoutouts to everyone else as well who pointed it out), and a solution has been found and will be patched in the next 1.2.0 version which should be out sometime early next week :D
It's seemingly a miscommunication between the elevator and the Unity physics system, so if the FPS is low enough so that the Physics systems clock is heavily desynced with the games clock, the player ends up sorta clipping through the elevator floor.
Thanks for pointing that out, it'll be patched next update!👍
