Hello Bob
I just installed loads of mods so it might not be this one that is the problem but the error message points to this mod and the error shows up while I load my savefile, in the end of it. I also tried a previous version but I get the exact same error.
Error while applying migration: Bob's Metals, Chemicals and Intermediates: bobplates_base_o.13.lua
bobplates/migration/bobplates_base_0.13.0.lua:8: attempts to index field 'sulfur-2' (a nil value)
