For those that weren't affected, users had been having trouble when asking users directly for items (buttons, scarves, and the like), in that they could ask their friends via wall posts, their friends could respond to said request, and yet no item was being sent. This issue has been fixed, along with a much-needed change in the selection of friends whose walls you can post on to begin with.
For many farmers (myself included), the list of three friends that I could ask for Snowballs was static and didn't change. This wasn't how the feature was supposed to work, as the users available to ask should be rotating once every 24 hours. Now, this part of the feature apparently works as it was intended, so feel free to start checking to see if you have any FarmVille players in that list of three that you can ask.
As a result of the inconvenience players have suffered as a result of these unforeseen glitches, Zynga is "evaluating" the possibility of offering some form of compensation to those players that were affected by the above Snowman issues, or any others that they have now fixed. There has been no statement as to what compensation users would receive exactly, if it actually comes to that, but it is promising to hear that the team is at least considering it.
[UPDATE: Users that were affected by the issue have now been given 20 free Farm Cash, as seen in the pop-up below. You'll see this pop-up the next time you load FarmVille, after this update has rolled out to your game]
What do you think would be a fair "reward" for those that have been set back as a result of these glitches? Were you one of the players affected by these problems with the Snowman event? Let us know in the comments.
