Well this isn't a glitch but when you spawn you spawn in the air instead. Also the place where the staircase starts there is no floor and I know you're not suppose to go in the bottom part of the tower because when you go in 3rd person you can't see yourself.
the staircase with no floor was left that way for you the builder to...well build something to connect it,and i guess no one has checked out the waterfalls,you spawn a few feet off the ground,that is not a glitch,i was thinking about making you fall a long way when you spawn,this map was about 2 hours work and a hour of that was probaly testing
