I crafted some items from the new collection of su2 weapons for woodworking, and i signed all of them. then my friend came to buy one and it came out unsigned, i checked him and it was unsigned so i got another one and traded him it that was signed. i noticed alot of the signatures in my bazaar were faded, and yes some items i did put on ah first, but they dont lose signature until sold i thought.
