HOWEVER I have noticed in the new patch that people in the druid area - both blacksmith and hobbit - even if you vanish INSTANTLY can set an aggro status on you permanently (this is regardless of the map travel thing, theyll aggro you from across the map). So, between quicksaves run into the tiefling pit and make sure the guards dont murder you.
I robbed both of them earlier today without this happening.
I unchained Astarion from the rest of the party and robbed the Blacksmith and ran away in stealth mode after grabbing 2 items. The blacksmith was shouting but no guard came. Next I stole 2 more items with my unchained ranger and also ran away in stealth. This time a guard came running towards my 2 other guys but no aggro on any of the 4 party members. I even sold back the old items I previously had equipped for good measure.
Note no timed turn mode or camp teleporting were used.
