The Adventure Zone: The Eleventh Hour (comics)

The Bureau of Balance has located yet another Grand Relic, and this time it's . . .time? A small mining town called Refuge has been locked away behind an arcane bubble, and somewhere inside it the Temporal Chalice is causing unknown mayhem. Taako, Magnus, and Merle are launched into their investigation, but they've barely had a chance to get their feet under them before the situation literally falls apart. When the town clock strikes noon, Refuge and its citizens are destroyed in a sudden chaos of flame and ruin, and our heroes' relic hunting - along with their lives - comes to an abrupt end.

But whoa, what's this? It's 11:00 AM, our heroes are alive again, and Refuge definitely hasn't just been exploded. Looks like a classic time loop, friends.
