When playing at crossfire.metalforge.net discovered containers limit is not taken in account when putting something inside more than displaying the message it wont fit in, but it actually is put into the container right after, i tried dressers, bookshelves, sacks and pouches, all same behaviour:
That won't fit in the sack * (open) (active)!
You put the staff of turn undead (lvl 33) in sack * (open) (active).

doesnt seem to matter if you are carrying the items or the container or they are on the floor, i think i tried every posibility.
