Blind isn't working, player characters get blinded, but NPC mobs hit just fine when being blinded with a spell.
Keys are visible in the "All" tab in the inventory and there are a lot of items that have the same description and names, but are different and doesn't stack with each other, like scrolls, arrow shafts and such. There's also items that stack that shouldn't stack, like magnifying lenses, repair hammers and other tools.
Please take a look at the inventory and how it works, there are issues with it that is actually making things a bit annoying. One is that you can't split stacks up and have one stack in a bag and one in the "All" tab in the inventory, as soon as you close and reopen the inventory, or close the inventory and talk to a merchant the stacks get merged in the bag.
