Error message refuses to go away

[PatrickBasedman]

So basically these past few days whenever I start a new game or load one, I get an error message and I click 'Ok' and about 10 seconds later it returns and continues doing this infinitely. Also the FindIt mod isn't working properly, the search box refuses to come up

The error message says this:

Object reference not set to an instance of an object [System.NullReferenceException]

Details:
No details

So I played around with my mods, removing any broken assets and mods. I started off disabling my mods and it fixed it. No assets were removed, so I ruled them off breaking the game.

I think the FindIt mod is broken, but I don't know why. Its essential to me.

I have my log here, I shortened it to the errors and it appears to be repeated, so skip through most of it. I believe FindIt and HideIt are two culprits here, but removing FindIt didn't work. But I will try again.

I've just been looking at another log file with similar errors regarding Find It! - but that mod has not been updated for a while. Did CO push a game update recently? (not sure how to check)

If it's broken, it's not the mod; it still works fine for most. Have a look at your Loading Screen Mod report, it's generally an asset, I find.

Having looked at your report, it looks like:
1. A missing building with RICO settings
2. a Hide It and RICO clash
3. a Hide It issue with a missing asset

Because the only Find it errors are at the beginning, and they all seem to relate to a single asset, it looks like that's just how that mod deals with missing assets. Check the Loading Screen Option to save an asset report, load the game, then exit and open the report.

Although Aubergine knows more code than me, so I might be wrong. I also haven't seen many similar error logs.

Thanks, I'll check that today. Hopefully I can fix it, I've tried a lot of things.

I also have a problem, I get an error message. I first thought of my mod that caused my game error. I try to disable all mods. but it remains error. after that I try to re-activate all my mods, and disable all of my assets. and my game is running as usual, I wonder if anyone here has experienced it? if yes please tell which asset is the cause of the error. Because my assets exceed 2 thousand. it's quite impossible for me to check one after another.

So I checked your log, and sadly, it does not mention which is the broken asset producing these errors, so you'll have to browse through your subscribed assets.

Here are the error messages for those who doesn't want to browse through the entire log, as it is pretty long (I see these errors being spammed by countless times):

Thanks for looking through it and highlighting a solution. I really appreciate it. I'll go through them and look, thank you :)

Something weird is going on with teh Find It mod - it's not been updated, so it's not the mod itself, however I'm seeing lots of log files with that error. I think either game code changed (maybe due to the 'free weekend') or some other mod is conflicting with Find It.

I have Find It!, and played the game only less 24 hours ago with a Facebook livestream (link: https://www.facebook.com/Meesmoth/videos/415782745916807/ ), and so far on that session, no errors were produced by Find It!, Hide It!, or even Ploppable RICO. I have 90 mods active during the session, but checking my own output_log shows nothing. Maybe this shows it is not caused by the mod or the game (free weekend cannot change something, as there are no patch notes or even official changes of game version).

It is just caused by user error because of people failing to organize their Workshop properly. Mine is organized much, so that's just one reason for me to have lots of Workshop without issues compared to other people.

Yup, I also have Find It and over 100 other mods and everything is working fine for me. But I've seen a few users now posting logs with the weird Find It errors in - I don't know what could be causing those errors.

Maybe it's Operating System specific? For those with the Find It errors in the log file, what OS are you using?

[leftbehind]

Hey, a mod dev just informed me that he's seen the errors before - they were caused by RICO assets that include something from a DLC but the required DLC isn't installed.. the problem then manifests itself in Find It mod as it tries to scan all the RICO assets and create thumbnails for them.

For me: Windows 10, version 1709, 64-bit (of course, as Cities cannot run on 32-bit systems)

No errors according to output_log, only harmless ones from European Buildings Unlocker mod.
