+			subchange = Further modify mass for Proc Parts structural parts, fix the cost of Proc Parts structural parts to be less than that of tanks (or about the same as the Steel tank)
+			subchange = Fix Proc Parts charging extra compared to ROTanks tank parts for a given diameter and length
+			subchange = Add some missing costs for some resources RO adds
+			subchange = Show an error dialog if Harmony patching fails during KSP startup
+			subchange = Move most RF tank costs from the subtank to the base part (i.e. adding a Kerosene tank will not actually increase the cost of the part, since the part is assumed to be a tank already, not an empty shell)
