So, me and my friend were playing when I realized two things that seemed off. For one, her sheild was going straight through her player, and it was on the wrong arm up by the shoulder. I also noticed while we were walking through a forest, her cats were floating 2 blocks above the ground and clipping straight through blocks. This may be due to experimental features on 1.17, and because it’s multiplayer but I’m not so sure. I don’t have a picture at the time, but I’ll get one later today.
