So it's been a few days since they finished paying out the rewards, but I still didn't receive the 5 Cetus Jugs for Greeting 60 people. I'm positive I greeted at least 60 people and probably even 60 unique people (in case it's just like the Friend Achievement where you -apperantly- needed to Friend 20 unique people).
So has anyone gotten Cetus Jugs? It could be that I didn't greet 60 unique people afterall (but it would've been like 59 then) or Aeria could've forgotten about rewarding them.
So far, anyone I asked did not receive Cetus Jugs, but none of them were certain of having Greeted 60 unique players.
