Well it all started when my game crashed. When I reloaded the game I noticed the rare and uncommon emotes were missing. I had them all and now they are gone. I reloaded multiple times and I still had the problem. Next the elytra, I noticed when in 3rd person while flying my elytra was invisible. I went to the overworld and the same thing happened. I went in all perspectives and tried taking off and putting on my elytra, and nothing worked. It's a minor bug but the emote one is big.
