FishVille Mushroom Mounds feature expires May 4
Here's the official note from FishVille moderator Susannah:
I just wanted to let you all know that the mushroom mound feature & so the mushrooms will be expiring on Tuesday, May 4, 2010! So, I'd advise you to cash in as many of your mushrooms as you want to over the next couple of days!
We heard you last time about needing clear warning more in advance, and so this time around you have 4 days to redeem your mushrooms.
