Thx

Thanks for this detail post!
6 months later now and the majority of the bugs you described still occurs.
Can't you fix the game instead of adding useless chrismath tree? Which by the way have nothing to do in a survival game like dayz... It's not Fortnite ! At least Fortnite is a free to play game which seems to be stable and not full of bugs, not like dayz which costs 50€ and crashes 50 times a day.

Are you sure it disappears? Don't you have an other object in your inventory where the battery should have gone (a scope...)
I notice that when you press triangle to equip something the priority goes to the objects that are in your inventory and not the ones in your hand ; which is not logic I think.
