Yeah, I tried it out over the weekend, and found out that Vantol was right: unlike old-world leves, Temple Leves DON'T repopulate just by completing the leve. You actually need to collect your reward, and there's no guarantee that you'll see a new leve there after doing so.

Very irritating, particularly if you're doing the leves just to add them to your completed list, and infuriatingly so if you're just trying to add a Large Scale leve to your completed list. Not very OCD friendly at all. :P
