I have a build with Ninja Backpack. I should see 89.5% Hazard Protection ( due to 9.5% on 1 pc) What i see is 79.5%. I look at the hazard protection stat where it list where all the stats come from. The game is NOT reading the Yaahl set bonus. You can see I only get the Ceska and Uzina set bonus. Tested in firing range, With bleed resistance mod to what SHOULD be 99.5% with hazpro+bleed resistance, I still bleed from Backfire.
