Unplayable Game: Simulation error: Object reference not set to an instance of an object

[Williamross93]

My game has been unplayable since about May. After the latest updates before that, it ran smoothly and quite fast. I since haven't been able to play, and my game loads a blank map with multiple simulation errors that won't go away even after clicking on them, forcing me to Task Manager quit. I have used LSM to try and recover from errors, and nothing worked. I have delved through Skyve, removed any mods wich clashed with others and updated every single mod. I removed all broken assets and still, the game doesn't work. I posted my output log onto the Steam forums, and someone suggested I increase my pagefile as they said it might be due to RAM. I did this (pretty sure I did it right), and alas, the game still won't load. When I started a new game, it loaded fine with no issues. Does this mean an asset in my game causes the error? I do not want to lose this save.

Here is my output log. https://www.dropbox.com/s/v6ywedm4qiujdxb/output_log.txt?dl=0

When you say you have removed some assets, were roads included? The game struggles to load when it's missing roads that were used in it

No, I only removed some invisible paths that showed as broken and some unused stuff

Actually any network used in the save, once removed, might break it - not only roads. Try subscribing to these invisible paths again, bulldoze them in the game and then unsubscribe from them again.

No luck; the game still won't load, sadly. Is there anything in my output log that may suggest what it is?

Nothing too specific that I can tell, no.

There's a bunch of d3d11 errors, which are usually related to graphic cards. Make sure your video drivers are all updated.
Other than that, it's probably either a mod problem or a memory problem. Double-check your mods with the list below to see if any of them is outdated - also make sure to check the tab "Broken".

Don't forget to enable the updated mods in Content Manager.


Also double-check if you've correctly increased your paging file size. The output log shows a lot of unused assets being unloaded to reduce memory. Here's a guide on how to do it:

Optional: Increasing the paging file size on Windows computers

On computers that have 8 GB of RAM, the suggested paging file size is 16 GB.
