Only Sealed Corridors from Sacrifice Fragment

I've been completing the prophecy that gives you the vaal orb when you defeat the boss in a corrupted zone by running sacrifice fragments in the map device.
The last 6 or so runs have all been Sealed Corridors.
I know it could just be by chance but it definitely seems like there's more to it than that.
The runs were all with angelic_reaper in 2.3.2b.

Bug report number 1,687,282,666.

That's how random works. Streaks are evidence of randomness.

I don't doubt that it is possible and I don't doubt that random events should have streaks within sequences of them.
However, it seemed fishy to me and if it was of high enough importance to GGG then they could copy my character and open sacrifice fragments themselves until they determined it to be chance or a bug.
I just opened up another Sealed Corridors to complete The Corrupt.
I am not inclined to run a bunch of sacrifice fragments personally to see if I am only going to get Sealed Corridors, as I am finally using them on maps and I don't want to convert them to vaal gems.
