In relation to Seabloom Algaculture here but the specific mod probably doesn't matter, just need something with a fuel value low enough.

Failed to load mods: Error while loading item prototype "cf-seawilt-1" (item): Unknown SI prefix: K in property tree at ROOT.item.cf-seawilt-1.fuel_value Modifications: Compressed Fuel

Kilo's SI prefix is a lowercase k, not K.

I updated it just now check if it works , if not just let me know

Failed to load mods: Error while loading item prototype "cf-yumako-pickled-5" (capsule): Value (5248800000) outside of range. The data type allows values from 0 to 4294967295 in property tree at ROOT.capsule.cf-yumako-pickled-5.spoil_ticks Modifications: Compressed Fuel
I actually don't even know what mod that item comes from, but evidently that function multiplying spoil_ticks needs a hard cap set.

all i can do now is update the mod changing and limiting stuff if i don't know the mod that problem came from. but still Update is out

If u want u can join my Polish Factorio Server to ask and send me stuff about this mod (link in my bio)

Same error in 1.0.3.
Pickling comes from pHactorio, but the prototype itself is generated dynamically, which is why I couldn't find it earlier.

new_item.spoil_ticks = math.floor(new_item.spoil_ticks * (3 ^ level))

This allows for spoil_ticks to be greater than 4294967295 which is causing the error.

I don't know Polish so I can't contribute much to a Polish Discord server.

sorry it took so long but i think its working now (there is no error on launch on my side)

and u dont need to know polish i can fully communicate in english and polish thats not a problem
