So I have an issue where tiles will fill with pollution and are bright red but they do not spread to the next tile. If anybody has any knowledge on why it may not be it would be a great help. Thanks!

The total spread rate is fairly slow. Eventually it will reach a tile where it gets absorbed faster than it can spread.

Biter nests absorb an extreme level of pollution. It will look like your red cloud hits a wall when in fact the nests are absorbing it to produce attack waves.

[Koub] I'll move this to "bug report" for the moment, assuming there IS an issue.
If it's not the case, I'll move it to wherever the topic fits best.
@OP : can you please attach your save, and your mod folder (if you're not playing vanilla) ?

You need to be more specific, as I'm quite sure that pollution spreads in 0.16 version.

Just for clarification, the mods I that are being used are, Additional-Turret-016 0.2.1, Darkstar_utilities_Low_Spec 0.16.8, Long Inserters 1.1.0, Nanobots 2.0.7, SimpleGodModule 0.6.1, Squeak Through 1.2.2, VehicleGrid 0.2.0, base 0.16.51 (obviously), and qol_research 2.2.6. Hope this helps

Can you post the save? I wouldn't be surprised if it's a value in the config of your save that you accidentally set way too high.

Yeah here's the save

Yeah, it's because diffusion ratio is set to 0%. (see screenshot) It's 2% by default. Did you set it to that manually?

Edit: the GUI would be somewhat different in 0.16, but functionally it's the same.

I probably did.

Is there any way to go into the file and change it?
