Sorry to pile on, but there also appears to be a bug where the script stows the box instead of dropping it (when picking it at a table). So when I try to trash the box, it doesn't get trashed, because it's in my backpack. Below is a log.

[tpick]>get #144553184
You pick up a weathered maoral box.

[tpick]>rub my vambrace
You gently rub the large translucent scarab set into the wrist of your padded golvern vambrace. The translucent scarab begins to glow with a white light for a few moments as a tiny mechanical arm suddenly extends from the interior of the vambrace.
The arm begins to prod at a weathered maoral box in your hand. A moment later the translucent scarab begins to glow with a bright green light as the arm quickly retracts.
Roundtime: 5 sec.
