Make sure your antivirus and Windows Defender (if on Windows) has cities.exe listed as an allowed/trusted app.

If that doesn't help, we'll need the output_log.txt to see what's happening. I recommend posting on the official support forums, so we can look into it. Steam just isn't great for support as you can't attach files here.

Did you restart the game between the first error and loading the older save? When you use mods, you should never to a 2nd load (loading a save after having already loaded one, without restarting the game), as this breaks some mods and causes weird things to happen.

It's one of two things depending on the size of the rocks. For large rocks (they're technically buildings) it's collision being disabled, which is usually something you switch on/off through a mod like Fine Road Anarchy 2.

For smaller rocks which are props, it's the settings you have with Prop and Tree Anarchy. Networks and buildings do not remove these props, only hides them, so they're back when you remove the roads or buildings. Enabling anarchy for props and trees stops this behavior.

That looks like a simulation error is happening. Your best options to try and recover the save from that is these two mods:

Subscribe to and enable both mods. Restart the game and go into Options, find the Loading Screen Mod on the left, then find and enable the Safe Mode options.... Read more

I suggest using Theme Mixer 2 instead. It lets you swap between theme settings much easier, so you can easily have snow without losing the settings from your regular theme mix.

With a 40GB full pagefile I would recommend you reduce the amount of workshop content you're using or upgrade your RAM.

You're running out of available memory. As you already have a full 32 GB pagefile my recommendation is to reduce custom content or increase your RAM. Also make sure to shut down any other apps that might be using memory while the game runs.

Does this also happen with the launch options -noWorkshop and -disableMods in place? And does it only happen to Azure Gulf?

How To Set Launch Options

• Right-click on the game title under the Library in Steam and select Properties.
  
• Enter the launch options you wish to apply in the box (be sure to separate each code with a space). Should look like this:
  -noWorkshop -disableMods
• Close the game's Properties window and launch the game.

Are you using any more mods than the ones mentioned? No snow sounds like you might have Theme Mixer and have changed the ground textures, which is being applied on a snow map.

My recommendation is to set the min and max size for your pagefile to 32000 MB (that's roughly 32 GB). 16 GB might be too low with workshop content as well.

Here's the Store page:
https://store.steampowered.com/app/1531470/Cities_Skylines__Content_Creator_Pack_Train_Stations/

If you mean ingame, then you are looking for the CCP tab, which is highlighted here:

For the Train Stations pack it's at the end of the public transport menu.

Check that the DLC is enabled in Steam and have Steam verify the game files.

This is correct. They are brand new assets made specifically for the packs.

They are in the list with the green tick. I bought them a week or two ago, downloaded them, checked them in the list but never seen them in the game...

Do you have the menu they should be in? Or is that missing too? If it isn't there, try verifying game files through... Read more

How can i see this list? I have the mod downloaded/

In Options you can find the mod on the left, then you can enable the option to create a log and see/choose where that log is generated.
