I used to disagree with this vehemently. They are intentional map design that requires awareness from the player. I still do disagree on removal, but I’ll concede they are an issue since I think Nightmares and Visions when they drastically increased the activation range on explosions. I assume it’s a bug but never saw or filed an acknowledged report.
Playing with Rumbler/Gauntlet Ogryn, either void staff psyker (but especially blast), or using any grenade or either bolt gun just sets off everything on any tile and it’s really fargin annoying in most situations.
