What Happened to TS?

There's the Red Skies Crossover, where a huge status quo shaking event is barely acknowledged in stories set in the same universe around the same time frame, and then there's this trope which goes way beyond that: a work in a shared universe isn't affected by a massive change in the status quo.

Maybe it's a work where the author has a lot more creative control than the studio. Maybe the work only exists in Broad Strokes compared to the rest of the universe. Or maybe the writers of the work don't feel like including the particular event in their work.

Whatever the reason may be, the work is completely isolated from the massive event taking place in the rest of the universe. Not even red skies, not even a token mention of the event, nothing.

Often leads to Continuity Snarl and Exiled From Continuity.

Examples of What Happened to TS? include:

• The Trope Namer is Mallrats. While most of the major characters in Clerks, Chasing Amy and even Dogma are accounted for in Jay and Silent Bob Strike Back and Jay and Silent Bob Reboot (as well as Clerks' own sequels), the only Mallrats character that returns in other View Askewniverse movies is Brodie Bruce, who never mentions what happened to the other characters.
• Masked Rider is part of the main Power Rangers universe, yet the show was never effected by the massive invasion of Earth in Countdown to Destruction. Furthermore, while the Megaforce Rangers get keys to all the past Rangers, they never get Masked Rider keys, nor is Dex seen in the final battle in Super Megaforce.
• Atop the Fourth Wall depicted the Entity "absorbing" the entire Channel Awesome Universe...yet none of the other shows were ever shown to be affected by it.
• None of the characters from Kong: Skull Island seem to be affected by the events of Godzilla: King of the Monsters. Skull Island and Kong do get namedropped a few times, yet when the time comes for all the Kaiju to be summoned in order to destroy the Earth, Kong and the Skull Crawlers are noticeably absent.
• Doctor Slump never acknowldged all the times in the Dragon Ball franchise where either the Earth got destroyed, or the Moon got destroyed.
• None of the Love Hina works seem to be willing to address the events of UQ Holder!.
