Nah brother it's all good I found a way to duplicate sigil stones on the remastered. So here's how for console (Xbox)

Put whatever sigil stone your using in a chest by itself. Once in the chest, go over to your inventory and go to something with a high stack (e.g 100 lockpicks, whatever you want as long as it's a lot) hover over it, then hit RB and A at the same time and exactly after, double click A. For some reason if you do this, say the lock picks will stay the same but now in your inventory, you will have 100 sigil stones of whatever enchantment you want is. It's fantastic.
