I'm pretty sure the Architect's Chamber is bugged, at least during Act 1 of the Campaign

I've played since the launch of the new league. I'm currently level 26 in Act 1 by solely trying to farm the temple.

Every time I've gone to the Architect's Chamber, it says "Room Complete" with no boss. I can open all 3 reward chests and access Xipocado's console.

On the Tracking Scroll of the Vaal, it says I have 3 Number of Xipocado, Royal Architect Kills, but I've not ONCE witnessed this boss.

Either it is intended to reach the architect's room and for it to say "Room Complete", or it's bugged in Act 1.

I even have the Fate of the Vaal quest, where it says "Defeat the Royal Architect in Atziri's Temple at level 75 or higher", but I've never not once killed the architect.

The tracking scroll simply tracks the kill if the room is "completed".
