I had a spate of bigger sets with parts errors - a missing 1x4 plate in the Police Station, a 1x1 DBlue brick instead of a 1x1 TransClear in 60197, missing 1x2 plate in the Harley... It was getting to the point where I was dreading building new sets wondering what the mistake was going to be that time.
The sheep I had a bag arrive a few months ago, loose packed in a jiffy style bag and a couple had marks from legs on the body. I found a thin damp cloth over my fingernail and scratch firmly cleared it eventually.
