Corruption zones no longer spawn

I'm playing the early access on ps5 since launch and this started when this latest season started(fate of the vaal). When I got to the end game everything looked normal there a corruption zone so I killed the maps and the nexus. Since then though there hasn't even been a hint of corruption on the map, I counted them here and it looks like I've done 83 maps since then in every possible direction but no corruption.

Does anyone know if this is a bug or what I need to do to fix it, anyway to reset the atlas even? Any help would be greatly appreciated.
