Apparently, it isn’t that hard if your on PC, but same difficulty on mobile as how it was with old yard map…
Text version on how to:
Get to the watchtower
Jump on left side on fence itself (right one doesn’t work due to hitboxes messed up!) and use shift-lock or first person camera to move camera to the right side, aiming at watchtower (being on top of fence)
SPAM Jump while slightly moving to the right side
Wish that your character will jump
If character jumped, run to the window on watchtower
Standing right at window, use “/e dance2”
Congrats!
Video variation:
Note: I have reset my character after doing this, so I don’t gain any advantage afterwards! GLITCHING IS BANABLE!
This glitch is also possible at the fence right of the tower. You just need to shift lock left 90° (zoom in on mobile) shortly before the dance2 teleport gets executed. This method is quite easy.
All windows/fences should work as they are the same size: SR, CR, EC, Sol and the door control rooms should all work if you can go with your face against the window.
