Anomaly #0017 is a rare event characterized by all other players in a ROBLOX game turning into blank robloxian models, completely freezing in place.

There are no known criteria for a #0017 event to happen, it seemingly happens at complete random, and it's unknown if it happens to all players in the server or just a single individual.

The following is a comprehensive timeline of events that occur during a #0017 event:

- 0 minutes: All other players on the server are frozen in place, and turned into blank, gray robloxians. Following this, all in-game audio is noticeably absent.
- 2 minutes: The skybox in-game begins to slowly darken, any and all stars in it have been noted to be missing.
- 10 minutes: Skybox is completely dark. Following this, black fog will slowly begin to roll in.
- 15 minutes: Black fog seemingly stops advancing. - 30 minutes: Game will begin to delete itself part-by-part. The length of this process can vary depending on the size of the game.

Attempting to reset your character during any part of the #0017 event will cause the game to crash, prematurely ending the event.

Due to the extreme rarity of #0017, many unconfirmed rumors about #0017 have been circulating. A few notable ones are as follows:

- Roughly 1-2 hours after the event first occurs, a sound reminiscent of crickets chirping will begin to play incessantly.
- A pair of white eyes watches the player affected by the event at a set distance.
- Sky slowly begins to turn a bright red.
- Player afflicted by #0017 suddenly turns into a gray robloxian, similar to the ones that appear at the start of the event.
- Large tendrils with a flesh-like texture begin to emerge from the ground, stretching upwards towards the sky seemingly forever.
