Hello! Were you AFK before maint? There was this guy running around yesterday and the day before expressing stack(s) of Sky Swords to random people. One of my guildie received them as well while being AFK on A1. They told me the name of the person, but I don't think I will mention it here.
It's not an IGG sided issue, but certain players doing that. If you were not previously AFK, I think you just missed the express notification. No other explanation, because you weren't the only one.
EDIT: Asked around in guild and found out it's 2 people he sent to, he was also on A1.
There was also a sale/drop event of these swords yesterday on A1.
EDIT2: Though now that I think about it, if you're not from Aries, then I don't know.
