The Knights of Knighton Quest can be completed.
003-Stronghold of Resolution
Reward: 5000 bits
Scan each of the required shields. As long as you have all of the required shields (0 power level is sufficient), you can collect the Quest Reward.
If 1 or more shields are faded, you have not scanned all of the necessary shields.
If there is a number in front of the chest, that means you have already collected that reward.
