This happend when i was playing /pk...
I just completed /pk1 and went to do it again when i was almost reaching the top the yellow container was gone.
I was like wtf! And i have no idea how that happend but i seems like it was only my game because another player got to the top didn't see him walk in the air or how the fuck it would've looked like because i was too busy taking screenshots!
You see, now i have no idea how the fuck that happend!
