Simulation: (failed) Object reference not set to an instance of an object

[jonralf]

Hi guys,

it's been a while since i last played the game, and in between that, I bought a few DLCs during the last summer sale. When I tried to load my save game, the simulation error come out but i'm able to load into the game. my city broke with almost no asset is loaded. i share the output log, tmpe log and screenshot in the following link:

i did tried to validate the game files via steam and go through the mod compatibility checker but doesn't found anything helpful (or I just don't know what i'm doing)

Hoping someone kind enough to look into my issue and thanks in advance

It looks like the problem you have is with the pedestrian path AI.

I would think you are using an old mod or broken mod.

If it is only the one mod you can try this:

tick recover from failed simulation and restart the steam and then the game
It helped me to get into a city

Let's start with old mods first. Here are some you should unsubscribe and replace with newer versions:

- Advanced Toolbar - conflicts with Resize It!, never have 2 mods that do the same.
- Demand Master is broken - there are a few other options like Super Demand, though nothing exactly like it.
- Advanced Road Anarchy - long broken, conflicts with Fine Road Anarchy 2 (which does everything you need anyways)
- No Pillars - you don't need this mod, it overlaps with other newer mods you have.

Remove those and make sore to enable any replacement you got. Add the mod Save Our Saves and make sure to enable it. Then restart the game.

Before loading your city, go into Options, find the Loading Screen Mod on the left and under options for it find the Safe Mode options. Enable all of them. Then try loading your city.

If that doesn't work, upload the log again, so we can see if something got solved.

thank you very much @snowflitzer & @avanya for the tips.

i enabled the recover from failed simulation and in Loading Screen Mod and my save game are able to load. I only lost a few road assets and all other things seems fine. didn't notice any mod that has been disabled but its been a while since i played the game, can't remember much what i have or don't.

once more, thanks for the guide. i think i should be fine now.
