Drowned Mob's Texture and model is buggy.

Samsung S6:
(On Android only) when re-entering the minecraft world from tab to tab on Android, the Drowned Texture's overlays (body, arms and legs) either disappears or the texture gets glitched. And with the model, the right arm is a little bit offset and the inflate for the overlays is to big which cover most of the armor. It be possible to make it like this (the first pic I modelled).
