I looked for almost an hour yesterday without finding anything. Today, I found the artifact in 5 minutes. Spooky voice, dark shadow formed, controller vibrated, push X to dig. All very simple. I'm convinced that it simply was not working correctly on the first day.
When you got today's artifact, did it tell you that you have to come back tomorrow for another one?
On my 2nd attempt to dig for artifacts, I found it. What I did to ensure success was make sure the Home Square was fully loaded. Then started to play the game and made sure to slowly search for the area to dig. It took me less then 2 minutes for my controller to vibrate and for a red aura to appear on my screen.
Hope this helps anyone else attempting to play the game again, after a first failed attempt.
I also re-tried today and this time found the dig inside a couple of minutes, and I didnt do anyhting different than i was doing yesterday so whatever the issue was may now be fixed. If anyone else was having trouble it may be worth trying again.
Mine was located by the Hed Kandi girl, on the same side as the excavation.
I just got the sarcphagus reward today. It is very big when I stand next to it.
Geez, they removed the mummy thing already. At only 3 or so days to get this with confusion reigning beforehand about what you were supposed to do, it must be one of the shortest lived rewards in Home history. I missed it, needed one more day. Oh well.
On a weird related note, you can still access Acorn Park Halloween in the EU.
