Node Controller Renewal 3.5

Try steam-runtime vs steam-native?
Is the save file being created despite the crash?
It might not show up in game, but be in the saves folder with a different extension. Renaming it may allow it to be loaded.
Try running Steam in a console so you can see if that spits anything useful out.

Same exception.

Added context that may help: this is under Ubuntu 22.04, kernel 6.11.0-26-generic, AMD Ryzen 5950X, Radeon 9070XT using mesa 25.0

I can probably do some more detailed debugging if you have places you want me to look but unless both these mods happen to be doing the exact same thing I think this might be a harmony bug.

What might suggest that it's *not* I've also tried loading harmony and Network Multitool only (again, requires harmony to be activated) and with that combination I am able to save without the crash. My understanding however is that harmony is basically replacing calls to some system libraries with modified versions. Possibly Network Multitool just never makes a call to anything problematic.

Going to weigh in here because I'm having the same problem. I *think* this is actually a bug in Harmony.

With *only* harmony and node controller loaded, I can create a new city, lay down a single road, save the game (locally - not steam) and immediately get a crash to desktop. Tailing the player.log while it does it we see

Notably, cities is sort of still running. There are a number of processes including Cities.x64 still active after this crash that have to be forcibly killed before cities can be launched again.

So, kill those processes then launch again. Disable node controller, enable intersection marking tool - another mod that requires harmony. Create a new city, lay down a single road, and save.

(I can't believe there's a 1000 char length limit here! Continued in next post.)

Alright, time for another round of experiments that will take a few weeks. I did nothing special except to install a version of Arch Linux as the base for Steam and Cities Skylines and NCM. And I always save my files to a local folder. So, I'll try using Garuda Linux and Bazzite and Cachy OS. Thanks for some feedback. I don't expect it to work.

Uncheck "save to cloud". Saving locally works fine. Not sure what's causing that as I don't have it here on Arch but I've seen it mentioned before. Consider trying Garuda Linux.

Did you do something special to have the game load with NCM enabled?
Have you thought about a gaming-oriented distro, like Bazzite or Cachy OS?
Also I guess a solution found for NCM would also be applicable to IMT.

@HamsterVolant Since I posted last, I installed three flavors of Manjaro Arch Linux and tested Steam and Installed Cities Skylines with the Node Controller Mod. So, the results are now mixed. The good news is that it loaded without crashing, with a big BUT; it now crashes on SAVE, and exit after save. I also tried openSUSE and a new distribution of Debian Linux. I would like this mod to work properly because it would give a good image of gaming under Linux. I'll be testing some more with my new Debian Linux Distro.

XCatcher act a little weird as it wasn't written for linux and uses hardcoded paths. So you may have the log in another folder a level or two up from where you'd expect it. See the comments on that mod for details.

XCatcher should have caught that NULL so see if you have that folder in the weird place.

XCatcher : no logfile (though it created the directory)

Hi
Will redo some tests later today and check the logs.
In the meantime, to give more details:
- Problem appears when loading a map
- There's no crash per se. The load freezes after loading a number of assets (about 7000 out of the 9800 subscribed). No error message, just freeze.
- The only way to exit is to kill the process

I have an ok rig I think (AMD Ryzen 7 9800X3D, AMD9070XT, 64Gb RAM) but anyway the game was running ok on the previous configuration too (i7 9700K, RTX2070, 64Gb RAM) until last year update which broke the 2 mods.
