Cities: Skylines comes with a massive workshop full of custom content that lets you customize your game to suit your playstyle, and if you use a lot of mods, you might be worried about what happens to your city now that patch 1.13.0-f7 is here. But fear not! I am here to guide you through the process and help you get back to building.
Since mods change how things work in the game, they are likely to break when a patch makes changes to the game itself, meaning your city won't load/work like it usually does. But don't worry, most mods update pretty quickly or can safely be removed, so you are unlikely to lose your city.
Just don't panic and if you do open your save, don't save over the file - save as a new file instead just to be safe.
If you play with a lot of mods
- Don’t open your city or cities yet, but wait until most major mods are updated, so nothing breaks.
- Use the links in this post to see which mods are updated.
- Disable all mods and start a new city (make sure not to save over your other city!) if you want to check out the new features. This can easily be done by adding the launch option “-noWorkshop” (without the quotation marks)
- Even if you have broken mods you might still be able to load your city, but depending on the mods things might be messy. If you do load without those mods, make sure to save as a new file just in case!
Will I be able to continue my old city?
Most likely yes, but it might be a few days depending on what mods you use. I'll help you figure out when you can safely start your city again.
Will ‘insert mod’ be updated?
Most likely yes - a lot of our awesome modders are working hard to get everything up and running again. But some mods will need larger fixes and as modders only have their free time, we might wait a while for some of them. Now is a great time to tell them how much we appreciate their work! And if there are already several comments mentioning the mod is broken, you don't need to comment. The modder knows and will update when they can.
Which mods are broken?
Follow this thread for a list of known broken mods, and updates as more are discovered and others are fixed.
Which mods do I absolutely need to load my city?
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. If any of these are broken you'll have to wait for them to be fixed to load your city again. 81 tiles is another mod you'll need to wait for to be updated if you have used it.
Then there are mods like Traffic Manager: President Edition, any mod that changes population numbers (like Realistic Population and Consumption), Ploppable RICO and Plop the Growables, which you can load your city without, but it's not a good idea as your city will be chaotic at best and fall apart at worst.
A good way to determine how much you need a mod is to think of what it does. If it makes some big changes to how things work in game, removing it will cause problems. If it's something that makes things more convenient for you but doesn't really change how things function once in your city, it isn't a big deal to get rid of.
Still having issues?
You might have mods that broke before this patch - maybe last patch or long before that. I recommend checking out this list of broken and abandoned mods to get rid of any old ones you still have. It's a constant work in progress, so it may not be a complete list. See the tab at the bottom on how to use.
