I have played through the story and am up to shadowbringers, however I realised that the Praetorium achievement is still yet to pop for me, I'm not sure if it is a bug, but I have gone into Praetorium a few times to try and get it to pop, but still no achievement. This account was created this year, July 2022. Naturally, it should just pop after going through playing through. Not sure if the changes to the main scenario dungeons make a difference?
