Cant finde any lightless voids or dark domains - even with the mod for boss modifiers

Level 96 - still havent found as single one, this can't be an RNG issue.
Please can you look into this? Other people seem to find those a lot.

I've bought Kulemak invitation to get the Abyss points faster, maybe this locked me out of this. But still I did that at level 90 or so - until then haven't found any too.

Respec that passive into something else.
I had the same problem and i wanted to farm kulemak but 0 bosses, respecced into something else now i got plenty of invitations.
Not sure whats wrong with atlas but if you want a thing just spec into something else.
