Standard Atlas Bug: Nightmare Maps & other boss maps not completing

After the 3.28 update, corrupted rare map in Standard unlocked the atlas but boss corner regions remain bugged. Nightmare maps cannot be socketed, preventing the last 5 atlas points. Shaper Guardians cannot be run—only Maze of the Minotaur appears, and completing it does not register or unlock the rest. Several maps (e.g., Augmented Distant Memory, Rewritten Distant Memory, Twisted Distant Memory) also fail to register as completed despite multiple clears.
