Is the challange cross contamination bugged? Or did I do something wrong

Tries two, and I think I did it the right way, yet none was complete. I'm not sure if I should try anymore.

1,defeat tier 4 harvest monster while delirious

bought scarab to guarantee tier 4 plant, with a delirium scarab and a harvest scarab,take the atlas passive that fog never dissipate, so once delirium fog is on, it's always on.

In map actually kill three tier 4 monsters, didn't counts.

2, defeat a possessed unique map boss while in a ritual.

Took a dune map for it's open layout, alt spam to get the unique boss is possessed prefix, use a ritual map craft

In map, drag the boss in a ritual circle killed it, even finished all four ritual encounters, didn't count.

And I even use the recheck achievements command, nothing happened.

For some strange reason it seems like you need to use deli orbs to get the challenge to work.
