Hi,
Just wanted to share an interesting/curious find :-) I have been parting out 12x 75954 - Harry Potter and the Great Hall. In that set there is a minifig of Nearly Headless Nick (HP145) and one of the minifigs of that character has a different leg than the rest of them. Instead of the original dark bluish grey leg, this one came with a right dark pearl grey leg. So the two legs are not the same color :-) Everything else is the same and the print is also correct. This goes to show that TLC CAN make mistakes - not something that happens very often (in my experience) :-)
