The extra damage from sneak attack on rogues does not work. Neither having an enemy within 1.5 meters nor being hidden actually adds the sneak attack damage. This can be verified by hovering over the damage in the log with the mouse and the extra d6 damage is never added to the attack (melee or ranged) regardless of being hidden or having a friendly close to the target. Since rogues don't get an extra attack like most other melee classes, the missing sneak attack damage leaves them very gimped and not worth playing atm. Some examples of the damage log not registering the extra d6 of sneak attack damage. The damage shown in the second image is from the killing blow to the enthralled schoolmaster for 6, without the extra d6 damage even though I was both hidden (as you can see in the log from the hiding effect being lost from the attack being made from the rear) and the target having an enemy (my party member) easily within 1.5 meters as she was able to attack him with a melee strike before my turn.
