Sometimes when you rejoin a server, your hunger and thirst bars wont show up in the new ui, and wont show up for a little while, even after messages tell you a couple times that your hungry / thirsty. Also sometimes happens even if you dont rejoin the server, but just stay on. One minute it will say i'm yellow hunger, I look again 5 minutes later, and its not showing anything.

As an aside note, would it be possible to add a bar showing your current blood level? I have a hard time telling how injured I am. I had a blurry screen yesterday, used 3 blood bags and that didnt even dent it, but it was only a minor injury. Turned out the blurry screen was a bug, and I wasted three blood bags.
