I think I see why there are too many offhand attacks per turn.
The game explains "Fast Hands" by "Gain an additional bonus action".
It's incorrect, see PHB pg. 97: Starting at 3rd level, you can use the bonus action granted by your Cunning Action to make a Dexterity (Sleight of Hand) check, use your thieves’ tools to disarm a trap or open a lock, or take the Use an Object action.
So Fast Hands gives new possibilities with the Cunning Action given at level 2. It's not an additional Cunning Action!
I haven't checked if that bug had an impact on the other bugs related to bonus actions being actually something else (previous post).
There should be a complete review of the rules related to combat actions, it seems pretty shady.
