@dag3737 The difference in damage total that you see in the screenshots you posted are not related to the bug on this thread which was already fixed.
Depending on which Phase you attacked in and which enemy unit you targeted, some of the damage will not be counted towards the damage total for the attempt.
Few things to take into account are:
- Damage to Darth Nihilus's Protection doesn't count towards the damage total (you have to get through the Protection and damage his Health in order for the damage to count) - you face Darth Nihilus in Phase 1 and 4 of the Sith Raid
- Damage to the minions doesn't count towards the damage total - Minions are present in all phases
It might help if you read the description of the Sith Raid to better understand the mechanics.
Thanks.
