Don't know if this is version specific or not, though been having issues where my friends' animations get reset to their default state every time I need to reload my own model or if they get culled from the view distance.
This ends up being a bit frustrating to deal with manually, since they end up having to reapply everything they changed so I can see them correctly.
Would it be possible to send the current state of each animation on a given model every time it is reloaded so that everything stays synced in these cases?

I believe i have seen something like this with held pose animations breaking when relogging or reloading. Seems to be an issue with priority, and can be fixed by increasing the animation priority of these animations higher than the others.

When reloading models, gestures and toggles seem to sometimes overwrite each other in the wrong order when they share the same priority level.
