[Issue] /sit emote not working correctly.

[Zwipp]

.- I cut distance by going trough a wall (Glade Partition).

Here is your issue most likely. If the chairs are close to the wall you're going through you won't be able to sit because when the unstick function kicks in and removes the hitbox, which lets you through the wall, it will also disable the sit function on everything nearby for what ever reason.

Just running away a good distance from the wall and then back should fix it though.
