I fixed my issue by publishing the animations under the group. If they are published under you, then they show up for you when you play in studio but nobody else can see them or they act funny.
it shows for everyone, including me and the other people working on the game, its only that the animation plays slightly differently if you play test it on the client
If none of these fix the issue it’s possible it may be a bug with the ClientAnimationThrottler.
You can see if disabling this fixes it.
It would be interesting if this fixes your issue, as I’ve experienced a couple of bugs from this feature recently.
