Since you're stuck on the launcher, please try the steps in this thread if you haven't already.

Toggleable Whiteness is a mod that is supposed to stop the automatic switch of views, so if you have that subscribed it would explain the switch not happening. With that mod you toggle it automatically by selecting the InfoView on the var on the left.

Transport lines should still be visible though. This reminds me of an issue with Transport Line Render Fix, which has become obsolete and now causes invisible transport lines. But that's been obsolete since Sunset Harbor was released and shouldn't be used anymore.

An easy way to test if it's caused by mods is to add the launch options -noWorkshop and -disableMods to Steam, then test on a new save. If the issue is gone, it's likely caused by mods.

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 ...

Have you set the district specialization for the district? That would be required for those buildings to spawn.

Sales on Steam will show how long until they expire, and if you add the DLCs you want to your wishlist, it will notify you when there's a sale including them.

Paradox support are investigating this but as it's only happening to some users and doesn't have a clear cause, there is no news yet. I recommend keeping an eye on this thread:

Originally posted by =Donkey=: Thank you Co-Avanya. reinstalled the launcher and to my surprise the game launched. What weird is, when i tried restarting it a second time I came back to the first problem.

Hmm that is strange. Best to contact Paradox Support then. Maybe there's a known fix for it, maybe it's related to the issues Steam is having at the moment.

How far do you get? Do you see the Paradox Launcher? Can you get to the main menu of the game? Is it a particular save that doesn't launch or can you not start a new game either?

Originally posted by RichNdeD .: I can start ONE and ONLY ONE game. If I try to save the current game, it over writes the existing game. Giving it a different name over writes the previous name. So, it becomes impossible to have a history of other maps from which to play.

We'll need logs to look into this. Please make a report on our support forum so we can have a proper look at what's going on.

You don't need to log into your Paradox account to play Cities: Skylines. You should still see the options to press Play and Resume in the launcher to start the game. Are those buttons missing?

Are you using any mods that affect traffic and public transport in any way? Or does this happen in a completely unmodded game?

We'll need to have a look at your log then, which unfortunately means I'll need you to make a post on our support forum as Steam doesn't let you attach files here. You can attach it directly when making a post on the support forum here:

We need the output_log.txt which can be found in the Cities_Data folder where the game is installed, usually something like this: C:\Program Files (x86)\Steam\steamapps\common\Cities_Skylines\Cities_Data

You can also find the folder by right-clicking on the game in your Library, select Manage and then Browse Local Files. Then just go into the Cities_Data folder and find the output_log.txt

Most props are not available ingame to be placed freely. They are available in the asset editor for decorating buildings.

Mods like Find It 2 let you access and place props in the game that are otherwise hidden. Note that they may not work fully when placed like that. Props with special markers such as seating and parking will not be used by citizens when placed directly in the world. They are only used when inside a building.

If you haven't already I recommend setting up a custom-sized pagefile of at least 32000 MB. Here are a few guides for how that's done:

If the game still crashes after doing that and restarting your computer for the changes to take effect, then please let me know.

Try verifying the game files through Steam to make sure the sound files are as they should be. Here's a guide on how that's done:

I would not recommend this solution. The issue with Citrix is that Unity (the engine Cities: Skylines runs on) thinks it's a graphics card. You may be able to run the game with this option, but it's running of the virtual GPU Citrix creates, NOT your actually GPU.

If you're on Windows 10 the easiest way is to uninstall Citrix and then install the version from the Windows 10 App Store. It lacks the feature that causes problems with Unity games.

Alternatively, you can reinstall Citrix from the Command Prompt using the following command:

Please check your subscribed mods against this list of known broken mods. If I remember correctly that error is from an old broken mod.

Yes, workshop planes work with Airport Areas too. Most of them will likely be medium planes as that's the default size, but there are also some made for the Airports DLC which provide options for small and large planes.

Are you using the mod 81 tiles? There's a known issue with it lowering metro tracks on the next load after purchasing a new tile.
