I cannot make Ironskin Potion. I have Lead in my world, if that matters. The problem is that I need to use the Guide to make the potion. In other words, I have to set the Work Bench and the Bottle near the Guide, and then click on HIS Crafting and craft the potion. Without the Guide, despite having all the materials and standing near the appropriate Crafting Station, I can't make the potion. This doesn't happen with the Regeneration Potion; I checked to make sure. I haven't checked with the others, though.
