Me and a friend found a particle bug

Me and a friend of mine found this issue where only i can see the particles in this brick, but she can’t

She already tried going in-game to see if it was a studio issue, but she still can’t see the particles, does anyone know why this is happening?

That is because you recently uploaded the image of the particle and roblox hasn’t moderated it yet. After roblox accepts it, others can see it too.

The same happens with decals and i think to meshes too.
