Arcane Ghosts - Loot Limbo

Hello,

I was curious... were ghosts designed to purposely not drop anything if they aren't hovering over Ground, or is this considered a long-time bug? What's the intention for this? The same thing happens to me when I kill (Toorc for example) in

Travincal; if he's pinned up against a corner (where the drops would fall behind him in the building were in) nothing will show up as a drop... I would have figured Blizzard would consider this a problem that would be fixed years ago, but today something happened that just upset me lol. I killed a champion pack of ghosts in Arcane, and heard the soundbite of a rune dropping. Yeah, it was probably trash, but man, why can't the drops load on the floor even if they were killed while hovering away from the floor?

I guess Arcane isn't the best place to farm because of this, it's such a shame because it's great for many reasons as is...
Thanks

I don't know if this is true because i never invested the time to check, so pardon me. But i remember hearing long ago that if they are clipping certain walls or objects they drop loot but it actually falls out of visible range. so its actually there, just hidden under textures. I remember hearing if you kill andy near the pillars or if you put meph up against the wall similar things could happen. Love to hear someone chime in on this though! i'm curious myself

To answer the OP, yes, anytime any mob (usually flying) dies over any impassable surface, such as water textures, cliff edges, or the space void in arcane, the drops don't spawn. It's a royal PITA and that's why whenever I face flyers (usually ghosts or crows), I like to back off and let them fly closer to a 'walkable' tile before killing them. I main a shooty shoot bowzon, so this isn't too big a deal or hassle, but still gets annoying from time to time, depending on the terrain and amount of mobs coming.
This is all from personal experience of mine from D2R and legacy LOD.
