Can anything be done..

[Busher]

I dropped an EE bag and a Light Burlap Sack with 2 TBB's in it once in Innothule. Positive I know who picked them up, but a gm told me tough luck when I petitioned. This was a couple years ago.
That being said, I've drop transferred lots of stuff, a few times upwards of 20K, and never lost anything else.
Underwater is a good place, and do use see invis first
