I was wondering if you were allowed to throw the snowballs at yourself, through the Snowtapult, for the achievement? I just tried one, and it counted toward my achievement, but I don't want to keep going if it's not allowed. Thank you!

I'm not sure why it wouldn't be allowed, since you still have to provide the snowballs yourself, and the person on the receiving end doesn't get anything out of it except a snowball on their HA for a few minutes. I figure it's no different than throwing them at some other specific person or using the random throw feature.

That's what I was thinking too, but then it made me think about stickers, and how you can't stick yourself.. Hmm.. I'm just not sure..

They implemented a feature where you can stick yourself, but it cost you 10k sP each time. -will find link shortly-

I would suggest posting in the Problems and Bugs forum or filing a ticket in this case, as it may be a glitch.
