As the title says - every time the torts drop moss, I get a combat message and log, with something like 20 iterations of "X tort has left some moss behind." is this intended, or have I mucked something up?

I am also trying to add Mossbrew Tonic to advanced brewing to take up fewer barrels, and I am unsure how to go about it. I included an example of an included recipe, and what I had hoped would work.

I'm fairly sure the issue is with the reagent line but I'm unsure exactly how to fix it
