Recently when noclip is off and i try to walk behind other players in vanish (happens since last update) i seem to get stuck.

I even recorded a video with vanish + colliders on - colliders off - vanish off.

I can confirm this issue. I can reproduce the bug in any shallow water areas.

Yep, I'm also experiencing this issue. It happens with 1.5.2 as well.

I'm not having this issue at all. Can you list your permissions you have granted to the group that you're in?

Also, are you using a custom map?

Edit: Yep can confirm this happens in shallow water. But ONLY in shallow water. My permissions for my group are listed below:

vanish.allow
vanish.damage
vanish.unlock
