This concerns only items with a weight below 1/9 of a pound. For these, the lighter an object, the harder it is to use remember place on.
To support moving from a heavy collection to a lighter-weight one, a ritual "Modify Memento" is available to priests of all gods.
P.S. Existing items with remember places are not affected at the moment. However, to be fair to younger priests who do not already have large collections of remembered cigarette papers, such items -will- be adapted in the future.
As previously announced on the boards, an additional weight check has been added to divine hand.
