Currently I'm equipped with a sprucecap, nettle shirt and pants, and clogs. All of those are gilded with Taproot lacing, which gives +1 survival on the sprucecap, the nettle shirt, the nettle pants, and +2 survival points on the clogs. However, my current survival level is +6, half of it coming from the learning points I spent to raise it, and the other +3 from my equipment. But the total amount should be +8 (+3 from the skill alone, +1 from the cap, +1 from the shirt, +1 from the pants, and +2 from the clogs) There are 2 points missing.
Is there something I'm not taking into account or is it a bug?
