Sure, go ahead.

Which update, the 2013-03-07 one? WTH, Valve? I read all the TF2 Update news on Steam (and occasionally on the Wiki), and oh boy there were a lot of updates and patches recently, but this change wasn't exactly made public!
Okay, the Wiki article on Stranges indeed mentions "Trading or using Gift Wrap on a Strange weapon will cause its counter to reset to zero and its prefix to reset to Strange. Using Gift Wrap will present a warning when attempting to use the Gift Wrap on a Strange weapon."
But the Discussion page to the article also mentions that indeed the change hasn't been made public. There's a link to a reddit article where it's implied: http://www.reddit.com/r/tf2/comments/19y9j0/wasnt_aware_they_fixed_it/
Can I enter your screenshot to the Wiki discussion as proof?

Yeah, the new update changed it.

Wait, what? "Scores on strange items will reset to 0 when wrapped." huh? But I thought the point of using gift wrap on stranges was specifically to prevent the counter(s) from resetting!?
To quote to the TF2 Wiki: "Gift wrapping a Strange weapon allows it to retain their rank upon trade." (Unless the "rank" in the strange's name remains, but the counter resets to 0, which would be even more confusing.)

Heh, cute name for the minigun.
