Getting an object reference error and I don't know how to fix it.

I was trying to build a canal system in my game, which ended up flooding my city and I started to get "Object reference not set to an instance of an object [System.NullReferenceException]" error code. It repeatedly opens and will not stop. I tried a few things to fix the problem.

First I tried opening another saved game to see if it was any of my mods or assets that are causing the problem but my old game worked just fine.

Next, I tried pausing the game and fixing the flood issue by diverting the stream. Once the flood was over and the town was not flooding anymore I tried unpausing the game to see if that changed anything, nothing.

Finally, I tried restarting the entire canal system and deleted everything. Still, I got this error message. I can see no other cause for the error than the flood, but I'm confused because I thought that this error was an object error that only has to do with assets and mods. Like I said my other game worked just fine with all the same loaded assets and mods, so I am at a loss.

I could use some advice please on how I can solve this issue. Please and thank you.

Hi,

I ran exactly into the same problem, after some thinking and trial&error I figured out the culprit in my case:
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=414025511
Removed and the error was gone. Just free-patch 1.13.0-f7 right now, DLC not active.

I suggest you check your older and preferably subway related assets, too. Hope it helps a bit.

I also have the feeling multitrack/multiplatform stations are currently somewhat broken, I can't set new stops.
