Deleted duplicate fonts and now some fonts have changed?

I just upgraded to Lion and decided to open Font Book and run the "Validate fonts" option. It came up with some duplicate fonts, which I removed to the trash. Oddly enough, if I run the same command it still finds the same fonts as duplicates. Also, I'm sure the fonts that Safari is using for the MacRumors forums is different now. Any way I can undo what just happened or properly manage my font situation? If I open the trash there appear to be 22 identical iterations of each font that Font Book flagged. Help!

I just restarted and it's the same different font.

Here's what it looks like now that I moved supposedly duplicate fonts to the trash.

And here's a sample of two of the fonts in my trash.

It looks normal to me.

The font is different from how it normally looks.

Here's a screenshot of the MacRumors Forums taken from the Guest account which has all-default settings. This is how it normally appears, and the original screenshot is how my normal account appears ever since I moved the "duplicate" fonts to the trash.

I should add that when I boot into Safe Mode, the font for the MacRumors Forums and a few other sites that display the wrong font display perfectly normally. How can I get my normal user account back to that state, then?

I'll finish this thread by saying that some fonts were somehow disabled. I reenabled them in Font Book and the few websites that displayed differently went back to normal.

Here's what Font Book originally said (and still says) when I go to "Validate Fonts."
