[2020] Array index is out of range?

Try enabling Safe Mode for the Loading Screen Mod before loading your save.

If that doesn't work, try adding the mod Save Our Saves, make sure it's enabled and that it's a fresh load (so restart the game first).

Have you tried saving as a new file, restarting the game and then loading that new save? Does it still get the error?

Hmm, at least some of the errors were fixed then. Did you try Safe Mode and Save Our Saves?

Originally posted by koyangi: I tried Safe Mode but nothing changed. Still 7 times to push "OK". Isnt Save Our Saves if you cant load your savegame?

It can help your save recover from simulation errors, which you have in the log you posted. So worth a try. If it doesn't help, you can remove it again.

That's good to hear. :) Can you upload a new log, so I can see the specifics of the error that's left? Hopefully we can get that one sorted too. :)

The error is coming from Surface Painter. After loading your save, open Options, find Surface Painter on the left, then click the "Update while map" button and wait for it to do its thing. Then save your city as a new file, restart the game and load that new save to see if the issue is fixed.
