Whenever I load a save game it duplicates all the items I got from science and fills my inventory, spilling everything on the floor. I had to disable the setting so I wouldn't duplicate thousands of items each time I join the game.
But as a sideeffect, you can no longer see what items you get by researching it directly in the tech menu. So as a workaround, when you queue (or start) a tech from that branch to be researched, it will display in the console what you will get.
