This is just a silly mod that makes every Cim want to move out of your city. It's pretty fun watching traffic and public transportation grind to a halt.
There are no settings. If this mod is enabled, any city you load will have its Cims move out.
Kudos to algernon (GitHub) for laying some of the modding ground work in their other CS2 mods published here. Hopefully I did the copyright stuff correctly. Some code and techniques were borrowed from algernon's Line Tool Lite mod. Please reach out to me on the Cities: Skylines Modding Discord (username ranthos) if I've done the credits incorrectly.
