Try recompiling with beta 28, and test the GET ALL issue. I put in a fox for a similar issue (reported by darkbluemonkey) earlier today.
It's weird, I think it's from the game. In 2, only the CASE CD is put down but it doesn't appear in the item list. In 3, a LOOK makes it appear.

drop all will be matched by adventuron, then all droppable items you hold will be submitted as individual commands (each consuming one tick). Having a custom handler shouldn't affect the item in a get all any differently to dropping it individually. There was a bug where in this area which coincidentally was fixed (hopefully) yesterday in beta 28.
Please retry with the recent version.
