Ok, all this can be explained. For nikre... i have no clue to that. I helped him out for some stuff, but I would never steal from anyone. He did mention that he had been robbed, and i told him i had no clue who could have done it. I would like to know what items were stolen, so I can better explain what could have happened there.
As for the duping:
The castle doors, i found. And i mined by myself. I can show you screenshots of my minimap history that prove that i went to a bunch of twilight castles and mined blocks from them. If you look in my ME system, search for a item named "Twilight Castle" Take it, and right click on my telepad two floors down with it. Then right click the telepad with a empty hand, and press "teleport" You will be teleported to a twilight castle, where you get those blocks in question, that was going to be mined out soon.
Vibrant capacitor banks:
This I also have a valid explanation for. If you look in my ME system, and search for a item... i think its called "Raid Base" or something. Anyways, someone sold me their old base, and we discovered a huge capacitor bank, that was part of the base. So as i now owned the base, we simply took everything and left. I still have the ability to get a telepad lock there. So when we mined all the capacitor banks, they would have all had the same charge, though some had more or less. That is why there are different charged capacitor banks. i think i have like three hundred with a lesser charge then the large stack.
