Weird character animation bug when in group, stuck looping last animation only on other player's screen #5610

Sometimes when in a group with another player, one player will constantly be left with the last animation looping on the other person's screen (it does not happen to your character on your own screen).

Examples:

Most common one is running in place, either on foot or mounted. It just doesn't seem to update the character's animation on the other player's screen to the idle animation when you stop moving.
Also gathering and crafting animations... the other player will appear to be hunched over gathering forever, or moulding their hands forever, etc.

This behaviour will stop on the other player's screen if you jump.

Note: this does not happen all the time, and seems to only happen when grouped up with another player. I haven't been able to figure out the condtions to get it to happen, but it happens often, and once it does it will not stop. Also, I have not seen it happen in dungeons yet, just grouped up with another person while questing.
