So i was in the underdark with a party of 6, one of them being Jaheria. I fought through the Mind Flayers lair, then heading into the Beholders cavern. I kill a few of the baddies, march on, then come across a few beholders and some mind flayers. In the middle of battle, Jaheria decides that she needs to go back to the Harpers Guild in the docks district. So i'm pissed. I'm left with Me (mage/theif), Minsc, Keldorn, Aeireeeriaiera (i can never remember how to spell her name), and Imoen. No healers. Uhg. I make my way somehow clearing the beholder caverns. At the time Jaheria left, she had 1 suit of full plate drow armour, and one drow sheild (+3 or something..) To make a long story short, I make it out of the underdark and go find Jaheira outside the Harpers Guild. She talks to whats-his-name about being executed, etc... I check her inventory cause she was carrying Keldorns Armour and some other peoples stuff. And she still had the Drow equipment, not adamantine dust! It is equiped and seems to be unchanged! w00t! Too bad she wasn't carrying 3 other suits and sheilds. she has like 1

00) strength or something from some gauntlets so she could managed
So it's bright and sunny out in the docks, and Jaheria is walking around in full Drow attire. How nice

Sorry if this is a known issue. I've got the latest official patch installed, btw.
