Im assuming that others have noticed that the "Daily Quests" (for which you receive rewards for spending certain lengths of time playing the game) aren't cumulative…

Its kind of aggravating how the clock starts over again once you get each reward. So instead of actually needing to have been online for the stated 10 min, 30 min, 1 hr, 3 hrs etc, its more like this:

Says "5 min" ~ Actual 5 min
Says "10 min" ~ Actual 15 min
Says "30 min" ~ Actual 45 min
Says "1 hr" ~ Actual 1hr 45min
Says "3 hrs" ~ Actual 4hrs 45min
Says "6 hrs" ~ Actual 10hrs 45min
Says "12 hrs" ~ Actual 22hrs 45min

Now, I don't know about anyone else, but I tried going for the so-called 12 hours, but seeing as I ended up falling asleep, it booted me off and I wasn't able to get it…

The times really should be cumulative...
