Problems with Harmony? Here are some solutions!
Network Extensions 2"

In the past issues occurred with Network Extensions 2. These issues have been fixed.

Users who used my custom version of NExt 2 can return to the workshop version.

Conflicting Harmony 2 provider mod
You can only use one Harmony provider mod at the same time.
Make sure you are not subscribed to "Harmony (redesigned)", an alternative provider mod that is known to cause issues.

Experimental Channel
You can unsubscribe the Harmony mod and subscribe to the experimental channel instead. The experimental version might contain additional fixes that are not yet available on the stable channel:
https://steamcommunity.com/sharedfiles/filedetails/?id=2399204842

Local mods
if you have any mods installed in your local AppData directory, please make sure that they are up to date! I recommend to use the workshop versions whenever possible!

Further support
If there are still errors once you've tried everything above, please upload your output_log.txt and post it here.

Windows: <SteamFolder>\SteamApps\common\Cities_Skylines\Cities_Data\output_log.txt

Mac: Users/<username>/Library/Logs/Unity/Player.log

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

Tip: To open the game install folder, right click your game in the Steam library, select Properties, go to the Local Files tab and select Browse local files.

"Technical Advice" from other people
Solutions given to you by other people are probably outdated, wrong or incomplete. If they work for you, that's great, but usually they only work randomly.

You can ask in this thread if those other solutions are feasible or not. I advice you to try the solutions above first.

@b.rense one of your mods (network/road related) is outdated and is causing the error.
I would recommend disabling all of your mods and then slowly enable them again until you find the broken mod.

It might also be that Steam didn't download the latest update for all of your mods. It might happen to unsub and resub those mods.

Boformer, do you know why when I load my old city from before the Airports dlc, the game cannot be unpaused? I get a harmony error on start up and when I enter the game, it says some airplane paths are not working. I've unsubscribed to everything flagged by the incompatability report generator and unsubscribed/resubscribed to the others to redownload them.

A Mod caused an error [System.Exception]

There seems to be a problem with the latest update of NetworkExtensions2. I am in contact with the author to fix those problems.

As of today, I'm getting a crash (inv kernel) if I start the game with Harmony active. All other mods can be activated and the game starts fine, only Harmony causes a crash. The log file in Unity is a bit wordy, but here's the stacktrace if that helps?

hmmm that's weird. Harmony mod doesn't need to be enabled in content manager, so if it works being disabled, maybe go with that for now.
