Help fixing a log

hey so my guild did our usual mythic farm of antorus and when we went to look at our logs after we killed portal keeper we noticed that the log was invalid because our warlock (the moron) had absolute corruption on for the trash, so some how it was still on the mob beating on diamond king and made the log invalid, i was wondering if there was a way to fix this? this is the log in question.

This also happened on Portal Keeper for me. The log was invalid for some reason.

No, not fixable. Your lock gains damage on other targets from having the DoT running on that mob, so the kill is tainted and cannot be allowed to rank.
