     - added a new recipe for cumene+nickel+arthropod blood into organic solvent
     - buffed bioprinting by removing primers from the pluripotent stem cells recipes
     - fixed that bioprinting stage 2 unlocked both mk1 and mk2 of brain printing. mk1 recipe moved down to bioprinting stage 1
-    - moved native flora smart farming down to chemical science 
+    - moved native flora smart farming down to chemical science
+    - standardized moss module speed bonuses to +100% +200% +300% +400% (final moss building speed uneffected)
   TURD:
     - added T.U.R.D unselect infinite tech to allow the indecisive to revert a single T.U.R.D selection
     - added a new T.U.R.D: the composter turd. why is it unlocked at military science? don't ask too many questions
