From the images you can see...I am wearing a plant fiber hat, and have a football helmet in my inventory. If I hover over the helmet, it shows a green 7(for a positive heat resist...yet the helmet has a heat resist of 0 and the fiber hat has a heat resist of 7. If the game is trying to calculate what i have vs what I hover(intend) to swap an item for...then the helmet should show a -7 for the attribute....20190612203212_1.jpg20190612203220_1.jpg
