Could be also problem in ep_engine. Particularly because tapagg totals are aggregated at slightly later time then normal tapagg stats.
Comment by Farshid Ghods (Inactive) [ 01/Jun/11 ]
this happens more often when switching to daily or weekly view
Comment by Steve Yen [ 17/Jan/12 ]
should this be moved to 2.0 dp4?
