CoreScript "AvatarMood" forces our Facial Animation compatible faces to constantly smile

Reproduction Steps

Play our game, create a save file or load an existing save file, and then play until you are able to move your camera to see your own face. Note how your character is smiling.

For us, this bug is only affecting our title Winds of Fortune, as we do not utilize dynamic faces anywhere else. However, this bug also occurs in the included Repro file, which is only a baseplate with our avatar.

Affected Devices

This error occurs for every person on every tested device, both in studio and in live

Expected Behavior

Our avatars (s15 skinned mesh with dynamic face support) should have a neutral face pose, unless if we choose to play an animation that changes it, as seen in this twitter post taken before this bug started happening:

Actual Behavior

Our avatars are constantly smiling.

This is because of the CoreScript AvatarMood forcing our avatars to play this animation:

moods_2_FaceAnimation - Roblox


We are currently looking into a workaround where we detect if the animation ID for “mood_2” is playing, and then if it is, halting it.
