Puff of Darkness Minion Guide Entry

Maybe my brain's not in gear right now, but to me the first half of the text for Puff of Darkness in the Minion Guide seems to be missing words or grammar, and it almost sounds like a run-on sentence. For reference, the entry:

Quote:

---

When this automaton resembling one crafted by a goldsmith hanged for dabbling in the dark arts was discovered, it prompted authorities to exhume the recently buried body. This, however, only confirmed their worst fears- that the coffin was empty.

I think I get what it's saying. Maybe fixing it would be as simple as adding a comma after the word, automaton? There are multiple ways to reword this instead of adding a comma, but I don't know the best solution. Also, I know this is really old by now, but it has some relevance again with the latest Anima Weapon quest.
