Any way to solve "Object reference not set to an instance of an object [System.NullReferenceException]"

[Dogge]

Hi, as many players I just updated the game.

When I load, it pops out as:

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

Details:
No details


I have updated the TM:PE already. Even though I disabled all mods, it is still there and cannot exit. So sad. I can start a new game and everything is fine but cannot load my old town... :(

Any solutions? Thanks!

Do you guys has same error code in your output-log file?

The problem comes when:
1. You have 81 tiles mod installed
2. You have more than 25 areas in the savegame
Just wait for the update of 81 tiles then

And 3. You have extra train station track mod installed and you have elevated or underground train station, Bloodypenguin is going to update the mod, just stay tune

Thank you!

According to the pinned discussion, the disabled mods still run codes in the game so it's no use. You need to unsubscribe them until the creators made a proper update.

I do not have 81 tiles mod. my city only has 25. but I still get this error. any other ideas? also not using any train related mods.

OK, sorry, but none of the above is 100% the answer (though disabling (some) mods may help of course - many of us have had this experience).

I have NO MODS active (since days - testing myself in vanilla mode) and I still get the Null Exception message. Game was fine in the early hours of today (CET). Not now. I had the extra train station track mode installed, but it was de-activated and therefore the game gave me an error for two assets: Boformer's Sunken Station and Gare d'Orsay - which are anyway not placed in the current city. So now I disabled these assets too. Shouldn't strictly be necessary. The mod message disappeared (confirming that action) but it made NO difference to the System Null Ref. Exception. The error is there in absolutely plan vanilla mode. Mods may make it worse ... but they are not the SOLE cause.

Please, Paradox developers get onto this... stuck at home and not able to play is really frustrating!

same, I unsubscribed to all mods. old saves are still broken. I am able to start a new city, but, I built up my current city so I could start using the DLC right away. not anymore...

OK more testing, in case any developers are reading this...

I can start a new city and save it quite normally. So the game works for new cities... on its own not wonderfully helpful. :-)

In my no-mods city, it seems the message comes in threes. If you press Enter three times quickly, it takes about 3 seconds until the message reappears and then needs again three "Enters". Then repeats. So either the game is testing all assets and finding the same error on hundreds of them... or it is stuck in a loop... Whatever, even after 15 minutes of pressing Enter, the error was still appearing and I gave up. Needs a bug fix Paradox, please!

I got the same error msg after loading the saved game. Hope the developer can fix the error asap :(
