Description​

I am using quite a few mods, but I did still get the error with mods disabled. Also I found a different thread that pointed to 81 tiles 2 but even when I disabled it I still got that error. Before I go over to the mod page and ask for help there I want to confirm it actually is a problem with that mod.
Additionally I did not have this error for a long time it just suddenly appeared during a session a few days ago. It is higly likely that this happpend due to the bug-fix update yesterday and there some mod that is misbehaving. I did check with skyve and I do not have any mod that is collidng with any other mod or needs immediate removal/replacement. The error is probably related to natural disasters and specificly tsunamis.
I can provide a complete list of mods and assets used if desired although many mods/assets from that collection are probably not actually used in the city.

Probably related to: https://forum.paradoxplaza.com/foru...ion-details-no-details.1587472/#post-28973873

You may need to go back to the previous save, before you started getting this error.

Maybe read up on the 81-tiles 2 mod and comments:

Steam Workshop::81 Tiles 2

steamcommunity.com

So I just loaded an older save and I am no longer able to produce this error with the exact same mods. I guess it just kinda resolved itself.
it occurs when a tsunami hits your city when you get this error and then save it does not go away.

Did you subscribe the 81-tiles 2? The old 81-tiles is made different and the V2 is suppose to be better.

Maybe your old save needs the regular 81-tiles?

But those outer two row of tiles aren't mean to be used, and the mod makes them unlock somehow. So there could be possible conflicts when switching 81-tiles mods in the middle of the saved game.
