The parable of the Rabbi and the goat

So apparently one of the effects of a DST change is making Monster Collection boxes exploration durations one hour less. (6 hr explorations are now 5 hrs, 3 hrs are now 2 hrs, etc.)

I haven't tried 30 minute explorations post-DST change (didn't think about it until now), but if the effect on them is as I think they are, don't be surprised if an unscheduled maintenance pops up soon...

EDIT: Asked a friend to test out 30 minute explorations post-DST. They're unaffected: they still have 30 minute durations.
