I've just collected 32 cubes, so i can open the 32 cubes door. I've also got the message that i can go there, but when i do, the door is broken.
It is in this location on the map:
When i got inside, it looks like the world is broken. In the room are no other doors. When i climb up there are 2 regular cubes, but nothing more.
Why is the door for 32 cubes broken?
