I wonder if agricultural science packs are spoiling when I still this mod? I currently use NoTimedSpoilage_1.0.1.
I'm not sure how you're managing that. Assuming you're talking about No Timed Spoilage, that mod is incompatible with "What's a Spoiling Plant?" That was a deliberate choice, as they both do the same thing. You really shouldn't be using both.
As to your actual question: I can't speak to how the two mods interact. However, if either removes Spoilage from Agricultural Science, then it won't spoil. If you just want that, then No Timed Spoilage will do it. If it doesn't, please feel free to post a thread there and I'll have a look at it.
