Every sunken ship that I visited, always had one of the bottom chests refuse to open when right-clicked on. It mostly occurs with the chest located underneath the room with the table in the back of the ship. Sometimes, it will be the other chests that are present. It takes the game roughly 3 to 5 minutes for it to register that the chest was clicked and should have opened. The game has no issue opening chests on command outside the ships, however.

What I expected to happen was...:
I expected the chest to open immediately

What actually happened was...:
The chest wouldn't open until a few minutes had passed.

Steps to Reproduce:
1. After locating a sunken ship, go to the bottom chest towards the back, in the small room.
2. Right-click the chest
