Hmm, I doublechecked with both Vagro and Abruzzo, before going back to the Greendale warehouse. I have the sneaking suspicion that on my visit to the statue, I didn't pay attention to the loot popup, if there was one, because I was busy de-webbing my party, because now nothing happens. Crap. Can't search the statue btw, it doesn't appear selectable when you do "look".
Do you remember what it was? With my luck, it's probably just a stash of coinage and some cheap bling. Sigh.
