I get an error when I focus on running boots which has -20 refinement as stats. In the PytChar class it seems refinement is not defined as a stat, but rather a skill? is the items_feet json entry wrong?
{
"id": "Running Boots",
"desc": "Boots made of firm but light leather. Just wearing them arouses a desire to run.",
"icon": "content/items/feet/rb.png",
"price": 125,
"sex": "unisex",
"chance": 70,
"badness": 75,

"type": "dress",
"evasion_bonus": 1,
"max": {"vitality": 15},
"mod": {"agility": 10, "refinement": -20},
------------------------------^^^^^^
"mod_skills": {"refinement": [0, 0, -0.08, 0, 0]},
"locations": ["Tailor Store", "Ninja Shop"],
"goodtraits": ["Athletic"]
},
Edit: If the json is incorrect, there are more items with the same issue elsewhere.
