The Soul Battery Fragment still has the same bug the Dwarven Spell Trap did before the January 12 update, in which this should have been fixed as well…
As you can see in the screenshot, the Energised Soul Battery Fragment did not unlock upon collecting all 4 souls, and unlike the updated Dwarven Spell Trap, simply double-clicking the Soul Battery Fragment does not energise it but tries to collect more souls. Please fix as this is blocking progress and if it was easy enough to implement for the Dwarven Spell Trap, I do not see how such a change couldn’t be easily made for the Soul Battery Fragment as well.
