Okay i was playing around in this map until i stumbled upon some weird hole behind the lockers i was confused i dont remember this being in the map before i decided to drop down it but nothing happened so i noclipped back up i decided to spawn some props and put them in the hole that is until i decided to just put random props that were already in the map until i got to the pink ball a set of numbers popped up (1302) i was confused until i noticed the music things have that code in it so i decided to put it in nothing really happened so i decided to press the mute button then a textureless button showed up and i pushed it which played weird creepy sounds then a entrance opened up after going down it it seemed my games quality went down a little when i exited the hallway it seemed like i was in a old version of the map the pool was gone there were no lockers or even music buttons i swear when i noclipped out of the hole i didint see this did it generate when i pushed the button... thats.. not.. possible though well i thought it wasnt however the next day (today) when i checked on it it seemed like the hallway just shrinks and theres no older version of the map weird?
