conqueror maps and favorite slots

anyone farming destructive play, and actually getting favorited maps when elder guardian maps and conqueror maps drop? I got some nice layouts favorited, but keep dropping Mazes, primordial blocks and flooded mines :-(

Is there a trick to it? I feel like the game used to take your favorited maps into account when dropping guardian maps...

It does, but I usually take Singular Focus in order to run only maps I want, it pairs well with 8 moded corrupted.

That beeing said I don't know if it is just my bad luck, or is it actually bugged, but after running someting about 20 maps i didn't drop even a single guardian, conqueror or synth map from a boss and invite as well, so someting might be bricked.
