NPCs disappeared in guild hall

After today's server problems (around 10 EST) all of the optional NPCs in our guild hall just disappeared. Needless to say Anet got a few displeased support tickets from Legend of Pi because we're not in a hurry to fork over another 480k for NPCs.

I'm wondering if this happened to anybody else? All other guilds in our alliance didn't lose any NPCs...

We have lost all our npc too.

But like 15min later they came back.

Yep, happened to a guild in our alliance, and I'm pretty sure they returned after a while.

Ours are still gone
