The error regards the "II-alien (recipe)" and "Error in assignID: item with name 'cb_alien_cold_artifact' does not exist".
It happens when trying to load the game up with the mod installed; I don't know if its because of a special incompatibility that I'm not aware of, or just the mod itself.

Do you have Frost Biters enabled? It's in the dependencies https://mods.factorio.com/mod/Cold_biters
I may have to look at the modlist otherwise because some other mod may be removing the item otherwise

I do have them enabled. But oh my fucking god, im sorry, I had the loot disabled in the mod config lol, that fixed it.

Yes, I did write to the mod author and he just said that there's a config that removes it. That was it. :)
