Overruned by abyssal map mode interaction with content(ritual)

In map ritual shows up as extra content but it is missing in map. It should be completely token over by abyss or stack like all other content or it is just a bug.

Had a map boss in that node didn't died.
Saved the ritual for later after killing boss but disappeared ritual content.

Boss was the act 4 priest that make the maze and thors rock. But culling make it bug? Don't get it. Hope it get fixed.
