A few bugs I found

The animations of holding a bow/item, Running, Walking, The Crouch animation is a bit weird, hand and feet animations don't work. And sometimes in creative mode the items will just dissapear out of my inventory and i couldn't put anything in my inventory. And the last few days, in my survival world, i will run in a direction and it will lag and i will teleport back to where i was 5 seconds ago. And if I break something like a bed, it will drop the item, but it looks like it's still there but it isn't because if you break it again you break what's behind it, plus you can walk through it. I apologize if this was a long message but there are all the bugs I'm noticing the last few days. I hope you have time to fix these problems.
