[Undrentide]

[Undrentide]

[Zenaku]

Noting wrong in our world just yet.

[Yucie]

definitely the Eorzean Rapture!

[Cendres]

Kids are gone too, happened right after Gridania started getting invaded and monsters spawned right near the playground.

DUN DUN DUN

Kids are still in Gridania on Gungnir, the music is still the same Gridania one though...

If other people are still seeing their npcs, its likely just you hitting the cap on characters displayed and so the npcs are unable to load. It has happened to me on occasion as well, though normally for only a single npc at a time. It happened rarely in FFXI too. The way to fix it is generally to walk away really far, so that the models that normally would be there would unload. then just walk back and they should hopefully reload properly for you. About 50-100 yalms or so does the trick normally.

Likely you're seeing it due to the sheer amount of enemies in the city atm, which is pushing up the cap on models displayed.

I just checked all three cities on Durandal and everything is normal.

This would make sense... If it didn't include Gridania when no one else was even in town, or moments in Ul'dah where there's no enemies up. :x
The NPCs are gone.

3x Nael van Darnus spawned INSIDE the Arrzanaeth Ossuary yesterday on Aegis. It was shortly after this that I noticed all the NPCs we gone from there. Admittedly, I haven't been able to check if they have reset since, but I would not be surprise if they were deemed killed in the chaos.

Not sure if it is related, but the patrons from the Quicksand in Ul'dah have also vanished on Ridill.
