[.15.x] Sudden crashes about one hour into a new world.

[Zevoss]

I wasn't doing anything particularly strange during the crash. I was just setting up steam engines for electricity. Then the crash happened, and shortly after I loaded the save again only to be crashing again. I have the save and log file.

Thanks for the report.
It is caused by pollution dissipation rate set to 0 and diffusion rate set to 100%, this causes pollution to spread in single direction to unlimited distance. I fixed the crash for 0.15.16, but eventually we need to limit these settings somehow, I think.
