Please explain your issue is in as much detail as possible.
Error occurs on every load, tried a vanilla launch and it didn't load at all either, suspect due to my railway 2 networks. I am using an M1 Pro MacBook Pro. Help would be massively appreciated as I am clueless reading error logs!

Can you replicate the issue? If yes, please explain how you did it.
Occurs every time I attempt to load save.

Check your mods against the list below and replace any that might be outdated/broken - also make sure to check the tabs "Broken" and "Incompatible":

[Cities Skylines] Broken & Incompatible Mods - Patch 1.17.1-f4

docs.google.com

If after doing that your problem isn't solved, try the following steps:

• Go to Main Menu > Options and select the Loading Screen Mod in the list on the left
• In the mod's settings, under General, select all boxes under Safe Mode
• Load the save and, if that works, save it as a new file
• Restart the game, disable the Safe Mode and open the save (the new file) again

Just tried this and, same error code unfortunately. I have double checked the asset list generated and I have all required networks downloaded so it's not that. Thank you for the suggestion though, what would you advise from here?

 

[Lucododosor]

The generated asset list is another action within the Loading Screen Mod, but not what I suggested actually. Have you tried the steps I said?


If you have and it didn't work either, try running a compatibility report. Read the instructions carefully in the mod's page:

Steam Workshop::Skyve v3.3.2.1 [Stable]

Tried this, only a couple broken mods. Removed them and issue is persisting. Not sure what the specific simulation failed I am getting means as it's not the one ive seen before.

Just tried that too, not working either.

Have you replaced those broken mods with the new ones? Some mods are necessary to load a save once you use them, so just removing them without a proper replacement might not help either.
Also, since it's a new simulation error, attach the new player log here. Thanks!

Oh when I said not the same simulation error as ive seen before meant that as in when there are networks missing in my past experience. It's still the same simulation error as in the original post. The removed mods were relight and shadow strength adjuster I dont suspect they'd be an issue removing in terms of loading a save?

I get the Simulation Failed and PropManager error as well. I can start a new game without issue. So maybe it is map related? If you use mods in the editor, then they can sometimes cause problems. Not to mention mod conflicts still possible. Just because compatibility report doesn't show then, doesn't mean they don't still happen.

Can you unsub all of your workshop and go back to a previous save (that wasn't overwritten recently) and find your previous working saved game, then subscribe all to the workshop and report any different results?
