Unique map and essence achievments

Hello, I have a problem because I spent so much time on farm uniques maps to drop unique map there for achievment. I did it twice but game didnt get me achievement, I tried it even with incubators and it still didnt work. Also they removed remnant of corruption and vaal orb dont work for the essence achievement too.

Yeah that essence one may not be possible, unless perhaps the remnants still exist in standard league. (I don't think they do, I checked some of my old essence tabs, and looks like they are repaced with vaal orbs. May not be possible.)

When I looked for a strategy for dream within a dream, I didn't find one, other than what you are doing, but I did find some references to it being bugged.

May not be worth your time, unless someone knows how to do it reliably. I have them, but I didn't intentional farm them, and they were likely done some time ago. I don't know if it is possible to do them currently or not.

Sometimes people make guides how to complete the challenges and achievements. If you are able to find a recent one, it may explain if/how they are possible.

both are bugged. And probably placed as "low priority" so that it will be fixed soon(tm)
