Mine dropped almost 80 points, but I figured it was because of all my new accounts/inquiries. Does seem like a lot of points. But since several of my accounts have aged 6 months I've seen increases in my other scores---but none with TU!
The thing is; TU hasn't updated many of my accounts since July!
