Factorio Forums

I installed mods and now whenever I try to load my game it tells me "Error in assignID, resource- category with name 'angels-fissure' does not exist" please help.

You can find your mod folder is %Appdata%/Roaming/Factorio/mods usually, from there you can delete the mods that are causing the issue.

Or instead of deleting the mods, you can download angel's infenite ores from mods.factorio.com and drop it in there.
