Information​

When reporting a crash, stability or performance problems, please use the Report a Crash button on the earlier screen​

[CLICK] I understand

Required​

Summary​

CTD without any log output. [Even on Vanilla] Game.Simulation.DeliveryTruckAISystem bug??

Steps to reproduce​

Loading the save, Wait to time 10:02 ~ 40 seconds , do nothing.

Expected Result​

Loading the save, waiting 40 seconds, then build a 20 lane highway, living my live happily after

Actual Result​

Load the save, wait 40 seconds and BOOM you are welcomed by your beautiful background picture.
Alternatively you are greeted by a huge error box if you have Skyve Safemode on, i believe this is the error that is crashing the game,
if theres no skyve safe mode you wont even see it, it will just CTD without a warning, it always CTD around the same time. I know that one sollution is to go into safe mode, waiting for the error, ignore it, save and play normally. Problem is that i have done this countless times now and this time it feels like im softlocked, the error starts occuring every 5th minute now making the loading time into safe mode longer than the actual game time:

Additional Information​

I have tried going into developer mode and clearing up all Cims and vehicles, but that seems to make the crash come even faster.
Ive also tried removing all tourist, homeless households, removing extra companies, reset landvalue, reset household wealth, basically anything i could reset ive tried but with no success.

In the attatchment below i wrote the exact error code crashing my game, and beneath it i posted other errors i believe are connected to it, they didnt show up in the logs either

I know that the long modlist above looks scary, but the game crashes without them aswell so they are probably not the issue here
My logs are listed below: The playerprev log is without mods, the other one is with mods.
There are 2 other posts with the same issue, but for some reason i cannot link them

I play vanilla and have on my largest city (1.3M) also a cdt every few seconds of gameplay.
No mods installed. And card without any message. Just closed game. Reported this already. Thought first: this would happen just on huge city but then I started a new one and after playing for a longer single session, it just happened again.

Thank you for your investigation, I’ve read many other similar issues with spontaneously crashes without any mods or other problems on saves.

Same here
 
I have an update to a potential bypass of this specific error, my save always crashed around the 10:02 mark, it has always done that, untill right now when i experimented to remove all road-outside connections, this has so far let me to get past the 10.02 mark, i will post any updates if i get other crashes

I'm also experiencing this error on one of my saves. Same exact behavior, issue persists even when disabling all mods. Safe mode gives the error message instead of CTD. Seems no fix has been found for this yet... in the meantime, this save is apparently bricked. It's possible that one of the mods is putting the savegame into this bricked state, but I searched through the Github of all my installed mods that might potentially be affecting the delivery system, and none of them are modifying `DeliveryTruckAISystem` or `DeliverJob`.

I have exactly the same issue and what is more interesting, exactly the same workaround works for me just for a few minutes. Just like you described. Then, again, I have to go to the Skyve SafeMode and save the game after the error appeared. It is truly frustrating, because everything worked like a charm month ago.

Could you please tell how you came to this that the save is bricked? Is there any mod or any other way to establish it?
 
When I say the save is bricked, I mean I cannot get past the crashes. I have tried the fix mentioned a few comments above regarding deleting all the outside road connections, but that did not stop the crashes for me. The only thing that stopped the crashing was to run in Safe Mode and get the "Object reference not set to an instance of an object" popups instead. However, Safe Mode is so slow that it basically renders the game unplayable, and even if I run in safe mode, go past an error, and then save again, crashing will continue as soon as I go back to regular mode, because it's not just a one time error, it continues to occur during the game's simulation. But, I can play other saves with no issues.

So, I would be very happy to find a fix or for the devs to investigate.
