I was doing instances yesterday,i was alone. First,I had the item distribution at 'leader distributes' but whenever I gave the items to myself,they became non-transferrable then,I changed the distribution settings to random,but again,whenever I killed a superbeing,the resource became non-transferrable as soon as i got it.I think it's bugged,it should be one time transferrable as it says 'it will be non-transferrable when owner changes
