It appears that mobs to not respawn in Villas anymore since the update. No more grinding to gain levels in Villas untill it's fixed. I don't know if this was intentional or not, but if it was, I would assume Funcom would have made a note of it in their patch release notes. I hate the Villas, but you can grind to gain levels there.

This has bugged for me once...at least the first time I've tried it. I had mobs in there just fine last night. 

 

Ditch the quests 

 

It'll initiate the cooldown...sorry...

 

 

Re-pickup the quests 

 

Should work. 

Fellow Guildmates noted that the Mobs in the Villas were back to normal last night. No "official" announcement about a fix that I saw from Funcom to date, but there is anecdotal evidence that a fix for the Villas may have gone into effect last night, 3 Aug.

Yeah, we saw a few notifications on our server that they were working on an issue with instances not resetting.
