All ghosts effect
Once I got the all ghosts effect while playing normally very shortly after opening the red door related to the secret on sector 289 with all the imps lined up behind. Recent Crispy Doom (5.8.0 IIRC), UV, no cheats or anything special. Tried to reproduce but can't. I guess it's related to having so many imps perfectly lined up? Maybe a warning should be added?
