As the title states, items like jetpack, battery packs, bronze armor do not show any damage bars so you cant tell how much charge is left or time left on armor etc. I feel like this has been around for a few versions now but have not seen anybody else posting about it.
I haven't seen this though apparently there have been a few new builds in the last days... I'm still on 2.2.6-63.
I did notice at one point though ( running an earlier version ) that when I died and went back to open my grave, my bronze armor ( and only that ) had fully repaired itself.
I should mention this is in Multiplayer as well
