Looking for confirmation about a discussion I was having the other day. So, I know that players outside your crew cannot "ping" an X on your map. I also know that once you hit a chest, anyone can come along and finish the dig, and take the chest.
However, the other day I had someone in my crew claim up and down that if you were allianced with someone, they could ping a chest on your map. Is there any truth to this? My strong suspicion is no, but I was wondering if any of you folks had actually tested this.
