What Happened to "The Observer"?

Lore hunters are currently scrambling to decipher the fate of "The Observer," the recurring NPC/Guide character who has appeared in every version since V4. mysteriousbox v20 updated

In V20, The Observer is missing. In their place is a glitched entity players are calling "The Echo." Instead of guiding players, The Echo repeats back the players' own failed solutions in a distorted voice, seemingly mocking their logic.

This change has led to a split in the community theory-crafting. One camp believes The Observer was a "developer tool" removed to make the game harder. The more conspiratorial camp believes the V20 update represents a "hostile takeover" of the narrative—that The Observer was locked out by The Echo.
