Expected Behavior

Urns and graves in a conquered structure should open when right-clicked to provide access to loot

Current Behavior

Urns and graves give the message that they can't be opened until the structure is conquered but once it is, they do not react to being right-clicked, or shift-right-clicked, or alt-right-clicked - I tried with both hands empty and still nothing. When broken, they don't drop anything

Steps to Reproduce

1. Find a structure that contains urns
2. Conquer the structure
3. Attempt to open urns

Possible Solution

No clue
