breach loot

mobs seem to interact with the atlas specs as intended however when the Breach specific instance ends and loot is generated, it seems to bypass map mods and any flags added, such as eldrich alters. I wonder if this is the cause for such poor drops being all over youtube as well as my personal interactions.

I took a unique duplicate eldrich alter and upon breach end loot generation the unique was not duped, however it duped normal drops from non breach mobs elsewhere in the map. It seems to behave closest to the way Ultimatum drops are generated, tho I haven't tested Ult with eldrich alters to see if they interact the same way with unique dupes
