+## Painted ME Stocking Input Buses/Hatches
+Multiple ME Stocking buses/hatches on a single machine cannot contain the same input, unless one of the buses is set to
+Distinct. This update alters that behavior to allow Stocking buses/hatches with different Paint colors to contain the
+same inputs, allowing those inputs to be present in multiple distinct paint groups.
