Well, this is kinda hard to explain and I'm not even completely sure it's your mod's fault, but I've got bspkr's Armor HUD mod installed and, well, apparently it thinks my melon backpack has started to break down, as per screenshot. And, as per screenshot again, the backpack seems to strongly disagree. Who is right? I am guessing the backpack, but I am still kinda perplexed.

Never mind that, remember they are not supposed to break.

Okey-dokey then :D if it breaks I'll sue you. Nah just kidding lol but if that happens I'll definitely tell you
