Ok, I was doing the quest "Brother Mine" as according to the wiki. I had 3 record of construction and proceeded to turn them into "a prototype" so that I would be attacked by it. However, after turning the record of construction in, the mob returned them to me without attacking. This part was bugged because the mob is suppose to become active and attack me so that I can win and then loot. I left sorcerers lab to talk with the quest giver, Envias, in thurgadin but received no help. I went back and tried to turn the records in again but it didn't work. somewhere in the process one of my quest pieces "record of construction" poofed. I then petitioned and the GM who responded said I still had 3 records of construction, however my inventory only showed 2. I re-petitioned because my first was dismissed, the gm said re log and of course I did. Re logging did not make my record of construction re appear. To conclude, i am now short 1 quest item and hope that it will get replaced and I hope that "a prototype" will attack me upon turning the record of constructions in again. Thanks very much for the help.
