Palmiero MIA

I recently came back to AO and have done one round of DB missions and one round of Alien missions, so not really got much experience with Palmiero, but my calculations says he was supposed to be back today/yesterday, and people I talk with ingame says the same. It was even mention of a lot of people petitioning yesterday.

I expected to find some info in the forums, but can't see it mentioned anywhere.
Has this happened before? Does he show up at random times or is it always at the same time?

He should have been spawned on sunday ( Dust It Off ).

I did petition, but only response i got from GM was that they will inform Dev's to look in to it

Looks like he's appeared :)
