Thanks!

In the meantime while playing on life servers: use your surrender action key combo to unrestrain yourself ... a helpful hint from one of our players.

While the screenshot I attached does not actually show the loop animation, it does show the first position of the successfully self-restrained character.

Every volunteer on our Altis Life server who tried the "sit down, press any WASD key" routine ended up with the same effect.

In some situations, it could actually be a useful feature to pose your character. But a proper unrestraining shortcut would be really helpful in that case.
