So concerning the murder investigation:
I gathered enough clues and confronted Esmerelda thus learning about Evelyn's involvement. I jumped through the various hoops and found she was indeed involved and had ran away to her beach shack. Well, looking at the map, I saw the quest marker was north of the town and slowly started working my way there. Eventually I came to a beach with a Waypoint Portal with a crab wandering around who told me about the talking statues. For all intents and purposes, the quest marker looks like it's exactly over the waypoint portal but I cannot click on it to activate it.
I need to know if this is a bug or have I missed something? The statues are protecting the cave entrance on the cliff, but they just say some item of great value is inside so I don't think that has anything to do with the main quest.
If it's a bug I need to know so I can report it. Thanks.
