This is a bit of a weird one, but I'm not sure if it is from an interaction between this mod and Bio Industries + More Bobs! for some reason. The technology for Fertilizer is listed as (unavailable) despite having its dependencies researched already. The only mods that indicate involvement with this technology are Bio Industries (which is the mod that adds it in the first place), ScienceCostTweaker Mod (mexmer) and More Bobs!
Here is a screenshot of what I mean: https://i.imgur.com/hphdLnT.jpg
