Animation different in studio than in-game

Hi, I’m currently making a game and am stuck on the fact that the animations of my arms are different than while I’m in-game

STUDIO:

IN-GAME

Expected behavior

The animation should be what you see in studio, though for some reason it is not. I’ve been trying to find a bug report or something on how to fix this for hours and have not found anything.

Thank you for your report. Do you have a rough timeline as to when this issue started occurring? Additionally, can you share a reproduction file that demonstrates the issue? Thanks.
