Like the title says.

Also to follow up so I don't clog the issues. I think you're missing a Rift Warden in Seat near the 2nd boss.

-edit. I revisited the Rift Warden spawn thing later and found that there is more potential spawns that aren't currently mapped in the addon. I don't know if this is intentional, but it does change the pulls depending on spawn count. I was attempting to make a preset for each possible route, which is dependent on the spawn of those rifts.

So far I have these locations as well as some evidence to their existence in m+(in the event you choose to map them):

Spawn by the water

Map Location:

Evidence:

Spawn in the shadow pool on right side

Map Location:

Evidence:

Spawn Near Boss (mentioned in the original comment)

Map Location:

Evidence:

Rift warden spawns have been hotfixed to only be the 3 that You can see in the addon since a month or two in m+

Defaulting to the current dungeon has been tried and deemed to be more annoying than helpful.
