Currently, the underlying animation asset used for the mood animation of the “:]” dynamic head is not owned by the “Roblox” account, but rather the “AvatarEmotion” group.
This causes the animation to fail to load in all experiences, producing errors in the output/console and Error Report on the Creator Dashboard whenever somebody wears the head on their avatar.
This has been an issue ever since the head was released on the marketplace.
All animations used in Roblox-created items should be owned by the “Roblox” account so that they can properly load in all experiences and not produce unnecessary error messages.
