The very first character I made checked the in-game mail and I did receive all 4 treasure maps.
Now I cannot deposit them into my personal bank. I was thinking I could put them there and then the character that I have in that faction area could use it. But since that is not the case, would anyone be able to tell me if the character that has them & opens them, are they the only one who gets the information off of them?
I'm thinking that either it is that way (which is fine I'm not greedy) or if not would it be that the information is shared between all my characters and that it then just becomes first come, first serve & once the treasure is gone it's gone.
