Placing Grand mirror fog inside breach quest area

Various curiosities happened when I placed grand mirror fog in the breach quest area.

1. when I first did this, it respecced all my atlas points, and actually removed 3 breach points (32/32 -> 29/32). I got to respec my >100 main atlas points which was cool.
2. it also only spawned about 5 delirium areas so I couldn't get to 100% deliriousness and do the simulacrum
3. it is impossible to create portals on the one on the breach tower
4. couple days later, I do some other grand mirrors and now the deliriousness of this area increased from 50% to like 150% so I could do the simulacrum, which I'm doing right now
5. it spawned a breach inside my simulacrum lol
6. dang a rare spawned in the wall and I can't do damage to it so i have to finish this simulacrum with infinite breach mobs spawning
