Different logs for same encounter

After clearing o12s this week I uploaded this log: https://www.fflogs.com/reports/mJXv69Vhpz3gZYM7#fight=last&type=damage-done.
Obviously everyone’s parse looks bad here and some ppl say that this total dps isn’t enough for a kill. My bard linked the log he uploaded:
This looks a lot better although having two different logs of same encounter at same time is strange. I can see that in my log there are missing some casts. In stream of my DRG i saw his ACT showing more dps than mine so it might be some my local ACT bug? Although its usually normal having different results on ACT but same in fflogs.

ACT bug yes. People can help you in the Discord. Means you lost events on the network.
