Lamps appearing on particles I'm using blender 2.8 and i have a scene with a donut with sprinkles for which i used the particles function. But when i try to add any object, every single sprinkle gets equipped with the same object, when i try to delete them, sprinkles disappear too. I'm guessing, it might have something to do with the weight paint i used for the sprinkles. You can check the file here:

Take a look at this image from your particle system:
Your are telling Blender to Render everything that is inside Collection 2 as particles, so every new object that you put inside the Collection 2, will be part of the particles. Just move the lamps to a different collection and you will be good to go.



Good Luck
