Ahoy !
I was wondering what are the conditions needed for the door of the cave to close while doing an ancient vault voyage. I repeat, this is not about the vault door that closes after 3 minutes, but about the cave door, the one that stays open even after the vault is done and closed, the one that has a big boulder as a "door". Because me and my friend had to leave momentarily the island to do a little fighting as we were bringing the chests from the vault door to the rowboat, and when we came back, the cave door was now closed, and the loot was "lost" inside, so I was wondering what are the conditions, so it doesn't happen to us again.
