+	/// to stack in the HQ inventory, causing them to lose their installed upgrades when equipped. The fix removes the 
+	/// check for the number of weapon upgrade slots on the weapon from the logic that determines whether the item has 
+	/// been modified or not, and leaves just the check for number of installed weapon upgrades.
