No actually…
I just tried the “talk_neutral” animation with every other mouth. It’s normal.
The “glitch” that is in the picture you posted isn’t a glitch. Idk why people are saying that it is. It’s literally the ending of the animation. If you put the character in “idle” which is a looping animation, then the character will be smiling/have those dimple thingies. When you make the character do “talk_neutral”, it ends with that mouth (the one in your picture) because it’s the end of that animation - “talk_neutral” isn’t a looping animation so it will have a fixed ending pose/facial pose. It’s been like that for ages…
Look, this character is in the idle animation. He’s smiling:
