Tried out the new IK beta. Noticed some strange things. My head turns way more in relation to how much I move it from side to side. The arm IK is also weird because it doesn't do the whole lean thing if your arms can go further irl, left and right are okay but when I put my hands forward it's like I'm hitting an invisible wall and it pushes my arm either left or right while also steering my entire chest that direction too.

Another issue I found was that on some avatars the head doesn't move at all and is instead tied to the chest for whatever reason so it results in only being able to look straight in whatever direction your body is turned towards.
