81 tiles is another mod you’ll need to wait for to be updated if you have used it. If any of these are broken you’ll have to wait for them to be fixed to load your city again. I don’t have a complete list, but generally mods that add a network like Network Extensions 2, More Train Tracks, Metro Overhaul Mod, One Way Train Tracks and Extra Train Station Tracks are needed to load a city once you have used the networks they add in your city. Which mods do I absolutely need to load my city?
