TYVM!
I am wondering about
<Warning: Overwritten large reference in Lux.esp [REFR:000CE0ED] (places FXMistLow01 [MSTT:00077772] in GRUP Cell Temporary Children of BlackreachWeatherTest2 [CELL:000237D2] (in Blackreach "Blackreach" [WRLD:0001EE62] at 3,3))>
Lux is overwritting some stuff in blackreach at cell 3,3, so according to your explanation the whole cell should be flickering because of the engine bug. Any way how i can teleport myself into that exact cell?
