Bug with Eternal Flame Rare Event Trigger with Orlea

About 26 - 29 chaos runs in I noticed I've only gotten the Eternal Flame rare unidentified area twice, both at low difficulty levels. At higher difficulty levels I didn't encounter the rare unidentified event even with zero system upgrade AND rare unidentified area chance increase fate. I did all my higher difficulty runs with Orlea + Mika + Nine, while I did lower difficulty runs with Rei + Mika + Nine.

Just to test out my theory, I did a difficulty 6 run with Rei + Mika + Nine again, and instantly on this run I got Eternal flame event. Unless I've just been super unlucky and then super lucky, I highly suspect that this is a bug.

PLEASE investigate this, CZN team. Getting 0 rare unidentified area after 25+ runs has got to be so improbable it might as well by statistically impossible.
