Old Sebilis NPC's Eating Charm-Given Items

[Gorbok]

This also happened to me recently but in Wakening Lands with geonids.

The charm pet dropped some of the items, but not the weapons it was clearly wielding. (Swarmcaller and Tome of the Eternal). It was DEFINITELY wielding the weapons, as it was proc'ing slow and visibly holding them.

So I do not think it is restricted to just Seb.
