The message for the verb 'remove' with an object that does not have the attribute clothing is not adapted.

The message is "You aren't wearing that." instead of "Taken.":

You can see a basket (in which are an apple and a pear) here.

>remove apple
(first taking the apple)
You aren't wearing that.

Or if no_implicit_actions = true (which is more confusing):

>remove apple
You aren't holding that!

The message is correct if I remove several objects:

>remove apple and pear
apple: Taken.
pear: Taken.

The grammar of the verb:

Verb 'remove'
    * held                                      -> Disrobe
    * multi                                     -> Take
    * multiinside 'from' noun                   -> Remove;

All seems to be better if I replace the token "held" by the attribute "clothing".

Verb 'remove'
    * clothing                                  -> Disrobe

You can see a basket (in which are an apple and a pear) here.

>remove apple
Taken.

>remove hat
You take off the hat.
