After the update last night, it looks like most MMD worlds—and I’m assuming other worlds that use special station setups—are currently broken.

From what I’ve been told, the issue seems to be that the local animation is breaking while the world animation continues to work.

What I’m seeing in-game:

Avatars start moving normally with the animation from the station.

After a couple of seconds, they stop and just stand still.

I’ve also noticed that if someone toggles something on their avatar while the dance animation is playing, it can cause the animation to break as well.

So far, this appears to be related to the latest VRChat update rather than an issue with the MMD setup itself.

Multiple worlds affected - here are two examples
