Hello again,
This time I've made sure the new Cerys update today didn't already fix the problem.
Fulgora Extended changes how the sludge on Fulgora works, with new recipes for filtering this sludge into materials.
https://mods.factorio.com/mod/fulgora-extended
If Cerys is installed alongside Fulgora Extended most of the sludge recipes are given a radiation requirement <200Bq.
(Specifically "Heavy oil extraction from muck", "Scrap sludge processing", and "Spicy scrap sludge forging")
(Weirdly "Chemical Muck Processing" and "Scrap sludge purging" do not have this requirement.)
If you also install Planetary Conditions you can no longer craft these sludge recipes due to Fulgora now having a higher ambient radiation.
If you then remove Planetary Conditions these recipes continue to be uncraftable on Fulgora, despite the planet now having the default <10Bq Ambient Radiation. I'm not sure how or why but I've tested multiple times in editor that adding Planetary Conditions prevents using the above recipes and they continue to be unusable after removing Planetary Conditions.
I've managed to fix an editor save by uninstalling both Cerys and Planetary Conditions, loading and resaving, then loading Cerys again. Hopefully this won't damage my real save too much since I haven't reached Cerys yet.
It's not technically a blocker since one recipe for getting heavy oil ("Chemical muck processing") remains usable, but it's a huge pain since the recipe is significantly more complicated, requiring steam to function where previously it wasn't needed.
Thank you for your time.
