Challenges not unlocking

I am having troubles with some of the challenges.

Mercenary: Demon of the Skies - I started a thirty second timer and stayed in the air for the entire time and a few more seconds. Nothing.
note: don’t go too high or it plops you right back tot he ground

MUL-T: Gotcha!
Pretty sure I killed the imp overlord w the PA but that said there may have been a bleed or something else. I would say I did it, but it is debatable

Engineer: 100% calculated - nuked a boss in about 3 seconds. Had 13x armour piercing to help it happen. Should have popped.

Are there some bugged challenges? Do they need specific difficulty? It’s a bit frustrating.

Looking for some help

i had an issue a few times with mul-t’s preon challenge. to make extra sure i killed the imp with it, i waited until there was ONLY an imp overlord, got him to near NO HP & then let my preon go off on its own. that way there was no chance for anything else to kill it. i failed omce in the same run i unlocked it because i wanted to bring his HP down just a LITTLE more, but my 3 ukeleles & will o’ wisps procc’d :frowning: So just keep trying!
