Last week I received several SR books from an aquanance, and amongst them was Queen Euphoria (as well as at least 3 doubles, the 2nd ed gm screen w/ contacts, Total Eclipse, Celtic Double Cross, predator and Prey, and Shadows of the Underworld.)
The QE has a sticker on the upper right corner of the front cover that says "Corrected Stock #7304" and has a small drawing of an ant under it!
Has anyone else come across a copy like this, expecially here well over a decade since it was published?

Also, anyone willing to trade a copy of Tir Na Nog for Harliqun's Back, PAOE, and Blood in the Board Room?

Yes, Queen Euphoria was published with the number "7205" on the spine. The correct stock number is "7304".

The FASA 7200 series are settings (sometimes with an adventure inside). 7205 is Universal Brotherhood.

The FASA 7300 series are adventures only. 7304 is Queen Euphoria.

I always wondered about that, it always screwed up who I thought it was set up but I trusted the editors. Bad editors, bad bad

That's not usually an editor issue; I'm not sure how FASA handled pre-press checking, but here [GoO], whoever lays out a book is responsible for pre-press checking. Typically someone else takes a quick look at the book as well, but the person credited as "Editor" inside the book usually doesn't; he or she is much more often responsible for text in raw form, before it ever hits layout.

[Pre-press checking being the stage where proofs come back from the printer, and you can fix errors - as long as you're willing to pay per fixed page.]

And for completness in this post...

FASA 7100 series where mainly rulebooks, although these crossed over with sourcebookater towards the end of second edition.

7305 was in fact the scenario Bottled Demon. One little point about that and Queen Euphoria is that the Seattle News-Intelligencer handout at the back of both those scenarios has the same date.
