after update all instances of the mining helmet headlamp now spawn at the feet.. this has saved over reloading the game, including earlier saves where the glitch is was not present.
Assuming its due to glitch caused by update, all mining helmets effected.
Assuming glitch is in positioning, Lamp still renders but fails to properly place on helmet.
Lamp Still functions on player and NPCs, First person view still renders normally as lightning is based on the camera rather than the physical model.
Glitch Affects player and NPCs equipped with Mining Helmet headlamp, Powerarmor headlamps unaffected.
Glitch has massive visual impact when seen on npcs at night as light is mostly blocked by terrain due to being half in the ground.
gltich discovered when equipping Settlers assigned to guard duty with helmets for visual effect a night. was very disappointed at the appearance of glitch.
