Yesterday the game crashed and after that the console froze with the messages in the image.

The solution was to delete the .map and give it to start. But now at every restart the same message appears and I must always delete the .map.

In addition the console shows some messages constantly (image2), this had never happened before, I just did a map wipe.

I must also add, although I don't know if it has to do with the problem, the power plant monument is bugged with a switch.

The map is procedural, generated only with seed. 

Have you tried a different seed?

Please, does anyone know anything about this error? I have seen that there is a thread with the same problem and no solution, a guy named @vanpaul had the same problem and I think he didn't solve it.
