NBS_LOSE -- Routines that lose noticeboards and items within noticeboards

The noticeboard system maintains counts of how many items have been found using NBS_FIND_ITEM and NBS_FIND_NTH_ITEM. The routines in this section can be used to indicate that noticeboards and items are no longer required. When a noticeboard is no longer required, it is marked for deletion. When an item is no longer required, its parent's item count is decremented. Normally, noticeboards and items can only be lost if the count of items found from them is zero (this is to minimise the chance of using an item ID to access a non-existent noticeboard), but this can be overridden.

NBS_LOSE_NOTICEBOARD:
Unmap a specified noticeboard
NBS_LOSE_ITEM:
Declare an intention never again to use a specified item
