[Bajorufas]

Hey, there is problem with liquids, vials etc. I have:
You see a trough of water.
I want to pour water on the ground and I see "You cannot use this object", no errors in console.

When I try put this water to vial then water disappears from trough but vial is still empty and there is error in console:
