In Multiplayer Shield, crossbow, Trident and spyglass all are Visually bug on the players.

This bug is Complicated especially Split screen for console and because on different platforms the bug looks different I think and I don't have all platforms.

All these items are tools and weapons, there is forms/looks of this bug while using the weapon or tool and while not using the weapon or tool.

To Perform this bug get 2 players or more and get one of there item and just look at the player/players

This is why Servers don't use these items.

So please bedrock team when making weapons and tools please check in Multiplayer.

Love.
