Cities: Skylines Dev Tracker

Make sure you use the right tool. A common mistake is trying to use the regular district tool when you need the Industry Area tool. Here's a pic of the one you need. :)

Ah yes! It's Citrix. Unity thinks Citrix is a graphics card (which ofc it isn't) and so all Unity games crash. If you need Citrix again, there's a few workarounds you can try in this thread:

Ah, so you're getting a simulation error. There's a few mods that can help fix that, so let's try those. Subscribe to these:

We'll need to see the output_log.txt (called player.log on Mac and Linux) to see what's causing it. Here's where to find the log depending on your operating system. To easily find the local files for the game, right click your game in the Steam library, select Properties, go to the Local Files tab and select Browse local files.

Windows
\SteamApps\common\Cities_Skylines\Cities_Data\output_log.txt

Mac OS X
Users//Library/Logs/Unity/Player.log

Linux
~/.config/unity3d/Colossal Order/Cities: Skylines/Player.log

As we can't attach files here on Steam, you will need to upload the file somewhere else. Here's a few sites you can upload it to, which do not require you to sign up first:

The absolute best place to start with mods is this Beginner's Guide. It covers the basics of what you need to know and has recommendations for where to start. It's gonna save you a lot of headache to start there. :)

Let's start by removing broken mods. Unsubscribe from these:

- Tree Brush (don't need it when you have Extra Landscaping Tools)
- Big City (don't need it with 81 tiles)
- More Beautification - get Find It 2 instead

I see that the Mod Compatibility Checker has checked your mods multiple times, which makes me wonder if you have done multiple loads. You have to restart the game after loading a city when using mods. Otherwise they get loaded "on top" of the first load, which breaks a lot of things.

With these mods removed and a fresh start of the game, does it then load?

Yup! I recommend avoiding Plop The Growables when you have Ploppable RICO Revisited. Just turn on the options for growables for Ploppable RICO and you're good. Using both comes with the risk that they conflict.

Originally posted by Elevator Hazard: You can use the Move It Mod and then ctrl Left\Right to rotate those items.

Not trees though. They can't be rotated manually. They live by their own rules. :P

The easiest way to find it is through the game. From the Main Menu go into the Content Manager, then find the Map Theme category on the list and find the theme in question on that list. You can click the Workshop icon to open the workshop page for it.

Alternately remove the . in the link and replace it with a space. Then Steam won't recognize it as a link and it shouldn't be automatically removed.

If you want controlled rotation, you can use this mod. Just keep in mind that it can increase memory usage a bunch.

You have a different issue, since you have both plenty of free RAM and pagefile space free. Please start a new thread about your issue. :)

Replace Advanced Toolbar with More Advanced Toolbar
Replace Auto Line Color with AutoLineColor Redux
Remove Fine Road Tool 1.3.7
Replace Fine IT 1.5.4 with Find It 2
Remove Metro station Converter (you should only use this if you do NOT have Metro Overhaul Mod)


Since you have Ultimate mod you also don't need No Fires or Pollution Remover mod. You should always avoid having mods that overlap like that as mods that do the same thing tend to conflict.

Try setting up a custom size pagefile of 32 GB. See this guide:

Sounds like you had a mod that enabled achievements with mods, which is either gone, disabled or broken.

I use the mod Steamy, but afaik Achieve It and Mod Achievement Enabler both work as well.

That sounds like an issue with the launcher. Try reinstalling it following the steps in this thread:

Originally posted by Halan: My Linux install sometimes crashes with "Receiving unhandled NULL exception" and sometimes the simulation gets stuck (I cannot unpause the game).
In the latter case there's no crash report or anything in my log. Is there maybe a way to turn on more verbose logging?

I do not have any obscure mods installed, just network extensions, and traffic manager.

Can you upload your player.log somewhere anyways? There might not be anything that looks out of the ordinary for you, but maybe we can spot something helpful. :)
