I have been egging my friend’s house all morning and it hasn’t budged from listing 5/10 times being egged, from yesterday. The number is not rising.

In your achievement? You only get one achievement for egging others' houses, it's not tiered. The tiered achievement is for having your house egged.

No, I am talking about me egging my friend's house. Her achievements are not going up, even though I have been egging her house all morning, Figured it had to be a glitch. My friends name is PocketMoonshy

Yeah that is weird. Is there maybe a page she's supposed to view or something? I have no idea ._.

Your friend hasn't been online for 12+hrs. They have to be online for the achievement to "populate." Once they come back online, it should work. If it doesn't, I would have THEM submit a ticket.

As mentioned above, the user has to actually be active for the achievement to update. :)
