I lost the root when exploring the ruins. I remember picking it up, but I was fiddling with my inventory and now it's not there. I have all the other key items and one empty vial. Is there a way to perhaps spawn this item? I've looked all over the ruins. Could it still be on the ground somewhere, or is it possible it disappeared after some time?

Nvm it was in my inventory, I just needed to click the right arrow far enough.
