I noticed it last night (before the patch), and later on some other players reported it in CA:
While passing/stationing on a random deed where you do not have permissions, you cannot drop items in crates in vehicles (cart, wagons, ships).
It used to work before, but now you get the [21:19:12] That would be very bad for your karma and is disallowed on this server. message.
It is possible to take out items from crates, or to put in / take out items from non-bulk containers or vehicles themselves.
On a side note, passengers still cannot take items from a knarr, only dragging them from the knarr in inventory works
