Even though you vote, you still have a XRAY. You were going for iron, diamond, gold, and sometimes coal. There was a very big tunnel system under ground.
I don't think Logan would think you used an X-ray mod without being 100% sure, he suggested you for trusted.
I don't know what is going on with this investigation fully but I have requested information, and I know that Nyssa wouldn't do anything unless she was 100% sure as well. So either you have done this or your "Cousin" has but your ACCOUNT has so your account will be punished (as Tabooti has said.).
