OK, so I finish the Poseidon Adventure and the sand squid, went to talk to the girl outside. And the question mark was greyed out. So I looked and it said that I needed to rescue the travelers, BUT i had just done that.
Then I noticed that ONE of the travelers had been rescued, but the other was not there> OK So I re-enter the sand squid dungeon to rescue the other and the dungeon was reset, didn't change realms, nor did I log out then in, I also entered alone. When I got there I had the diver down quest back, along with the Poseidon Adventure.
I have done this many times (on other wizard) so I know I didn't mis anything with this one. I took screen shots to back this up, can someone please look into it and get back to me.
