Sextant broken: no additional two maps (bodyguards present) 3524715868

Sextant mod in question:

UNIQUE BOSSES ARE ACCOMPANIED BY BODY GUARDS. 2 ADDITIONAL MAPS DROP ON COMPLETING AREAS.

Awakened sextants were used.
Charge 1/3 was consumed on activating.
Body guards were guarding the map boss, but no maps dropped on completion.

Map: Residence T14
Via map device...
Master: Alva (complete before engaging boss room)
Scarab: Rusted Breach (one breach, not completed)
League: Anarchy (exiles dead)

Other sextants active 2/3 after activation:
1. Players and their minions cannot take reflected damage. Areas contain 5 additional packs with mirrored rare monsters.
2. Areas contain two extra strongboxes. Strongboxes in areas are corrupted. Strongboxes in areas are at least rare rarity. (opened)
3. The first three possessed monsters drop an additional gilded scarab. Areas contain an additional tormented betrayer. (spirits killed)

Side note: Spirits, even if positioned next to rare monsters, simply vanished instead of possessing mobs. What a waste!

These bugs cause anger and dissapointment. So much that I'd rather write a long bug report than continue playing the game. Got it?

UPDATE!
It worked nicely in T16 Promenade.
Second try T14 Residence (last sextant charge) and no maps dropped!

I can confirm this bug. I provide details in the way that the first post did.

General information:
- Bug reference number: 664.675.789
- Charge 1/3 was consumed on activating.
- Body guards were guarding the map boss, but no maps dropped on completion.

Map information:
- Map: Lava Chambers (T16, Rare, 20% quality)
- Prime Sextants used
- Master: Alva
- Scarab: Rusted Breach
- League: Breach

Other sextants active 2/3 after activation:
- Areas can contain breaches. Areas contain an additional breach.
- Player's life and mana recovery from flasks are instant. Areas contain 6 additional packs of monsters that heal.
- Players and their minions cannot take reflected damage. Areas contain 3 additional packs with mirrored rare monsters.

I want to note that my case shares Alva as master and a rusted breach scarab, as well as the "cannot take reflected damage" sextant mod.

I died 2 or 3 times in that juicy map and completed the last 3 incursions to prepare the temple as well as all breaches, before entering the boss room.

This bug still seems to be present!

I just ran a completely different setup with a different map, different sextants, different scarabs and a Zana master mission.

Sometimes, the additional map just does not drop for whatever reason. In other cases it did work.

I will not post a lengthy bug report again as this seems to be a problem with how this sextant is implemented.

not really. It's not a bug and working as intended by GGG (confirmed several times)...

The reason is that the 2 maps that could drop is blocked by the Atlas setup.
So if your atlas is 100% full with all the stones, only T13+ maps can drop.
So if the map drops from sextant was going to T10 and T14, only the T14 will drop and the T10 will be blocked.
