Hello, I played a game of Factorio this morning with this mod installed and had no issue with my save file or the game running at the time. After work I got home and am greeted with this message:
Failed to load mods: Difficulty normal: Cycle in technology tree detected
Production-science-pack
-> angels-metallurgy-4
-> powder-metallurgy-3
-> angels-glass-smelting-3
-> advanced-electronics-2
-> sct-lab-t4
-> production-science-pack
I am running a whole slew of mods at the moment, most notably all of angels, bobs and seablock.
