Abnormality #0002, designated "gm_buriedsky," refers to a non-indexed map resembling a corrupted version of gm_flatgrass. This map is characterized by severe lighting anomalies, visual glitches, and temporal desync. It is not accessible through the standard "Start New Game" map menu and can only be loaded manually via console (map gm_buriedsky)-if it exists in the local files at all.
The map's skybox renders below the terrain, causing an effect where the sun appears to rise from underground. Soundscapes include metallic ambient wind, untagged and unaffected by stopsound or audio sliders.
Typical effects reported include:
Sudden teleportation back to spawn without user input.
Toolgun menu ceases to function.
Environment freezes and is unable to be changed, whether it be props or entities.
gm_buriedsky was first mentioned in Facepunch (Feb 2017) in a thread titled "Map keeps teleporting me back randomly?" The original poster claimed they did not download the map and were unable to delete it after exiting the game. Several users later reported similar files appearing.
As of 2022, gm_buriedsky along with all of its copies were purged from GMod as a whole in the June 2022 update. Steam users who still had files of the map were terminated off of the platform and no known footage exists.
