Blizzard retroactively timing M+ runs?

Hey all,

I noticed this today. I missed timing a +11 PSF by some 10 seconds a few days ago. With reset, they extended the timer for the dungeon by 90 seconds, but as of yesterday evening, that run was still marked as over time because it happened when the timer was still shorter. I never expected anything different.

Well, today, I went back and looked, and both the in-game UI and raider.io are marking that run (and another close, formerly overtime +10 PSF) as being timed. My dungeon rating, both for PSF and overall, is also now higher to reflect this.

Of note, I still don't have the Keystone Hero achievement or portal for PSF (I'm assuming that whatever they did to update the runs didn't trigger the achievement completion criteria).

Is anyone else seeing anything like this? M+ has been my main game mode for a while now but I don't recall seeing this sort of thing happen before. Usually, if the timer gets extended, that's only applied for future runs, not retroactively applied to overtime runs.
