There seems to be a glitch in the St Patrick's Day challenge 2. You need to place a metal detector near 2 log piles (to the right of the leprechaun you give the pots to) to find a pot. But there is no pot there. I received the experience but no pot. How do I move on? I found all twelve pots but this one doesn't show!
EDIT - that link does nothing for anyone, just tries to load Diggy in Facebook.
