I have a party that I have built up to level 3. Right now I have mink Inoen and that evoker chick.I cleared out the mines and rescued minsk's friend which is a little backwards. Then I came to the Friendly Arm Inn and they are not there at the bar. Did I do something wrong?

Maybe you were too late?
And after having cleared the Nashkel Mine and the Gnoll Fortress CHARNAME no longer needs babysitting from Aunt Jaheira and Uncle Khalid.

This is real Choices&Consequences™
Strange that Baldur's Gate is not more popular on the RPG Codex. ;-)
