I’ve noticed this multiple times. I’ll have a character do a talking animation but he/she just stands there doing nothing. I’ve tried to do a different animation and it’s the same. And also, I’ll have written one animation like react_gasp_dismayed but when I save it and go back, it’s changed to yawn_bored…
Maybe you can try submitting a ticket to the team, or re-starting your computer. If it’s a glitch, it should be fixed either way.
