So, a few days ago, I downloaded the new 1.8 beta on my Xbox One and my Android Samsung Galaxy S9. Basically, I went to look for a skin and what happened was that basically every skin pack's skins were missing the Left Arm and Left Leg. And every skin with slim arms, such as the Alex skins, had the classic 4 pixel arms. Not only that bug, but the hand was also glitched. I was mining some blocks and my hand was going to fast to the point where it looked like my hand was having a seizure. i was just mining some blocks and this happened. Not only did it affect me, but it also  affected my brothers and my friend. I don't know why this is happening. I really would like it to be fixed. As it is really getting on my nerves.
