JP Skipper seems correct with his assessment. The old Clementine Lunar Browser 1.5 is no longer active, now all they have is the new one:

Anyway I've never liked what they've offered with Clementine, it's always been these big obfuscated maps with no image references. So even if you find anomalies, trying to trace them back is often a problem. Your only other option with Clementine is either at
Map-A-Planet:
