I have been trying to deal with this shield bug ever since 1.17.0 came out recently. The shield, instead of being held with the left hand of the player, it stands on the left shoulder. While in first person, the shield would block the camera, seriously affecting gameplay. I also know for a fact that when my friends come play on my PlayStation 4, it affects them too. This bug has been on here for awhile, and I hope you have it fixed. Thank you.
