My BLM logs once uploaded are 200-300 DPS lower (it is missing around 180,000 points of damage) than what ACT shows, after further investigation it seems that once the log is uploaded it is missing Fire IV, Blizzard III, and some thunder ticks from both hardcasted Thunder and Thunder Procs when compared with the casts ACT has logged.

Upon further investigation other encounters are missing different casts, for example one encounter is not missing any Blizzard IV casts but it is missing Blizzard III casts.
