Update on the server - it looks like turns aren't refilling at all. No new turns accumulated for me recently, and no spells refilled for the last two dawns. Also, no battle have happened with any of my garrisons overnight, which is unusual. Looks like the scripts for updates are broken, so you won't get new spells, turns, or monsters moving/battling/refilling most likely.
Looking at the number of monster groups in the world, currently 4731, should give an idea of the state of the scripts. You can still use up any accumulated turns you have when you log in, so people might still be able to kill a few monster groups thus reducing that number. The number of monsters will continue to drop for a while then as people log in and take actions. I'll keep an eye on the monster groups in around 12 hours from now, to see if it keeps dropping or ever bounces back.
Edit: monsters on the map are accumulating, it went up to 4999 monster groups on the map, but turns only went up 1 hours worth for me since I first posted this 7 hours ago. Might wait a few of days and check then. If turns aren't accumulating fast but monsters are regenerating then the overall monster density should go up a lot, meaning playtime will be more effective once turns fill up.
