I really hate it when it happens, over 100 mods already updated but without this mod https://mods.factorio.com/mod/bobsflowcontrol-updated I cannot continue my world on 1.1... anyone might have any idea ? I used a lot of custom corner pipes...
I managed to fix it by myself thanks to author who left a path for those AddTech tags
so as error says line 617 also 618 and 619... in data-updates.lua
so I checked the Bob's mods what was changed and old "alloy-processing-1" now is just like this "alloy-processing"
seems to be working as intended :o
