Found that Mom's Bracelet cannot move up some regular-appearance stones.
Those stones acts as a lead, that an explosion explodes them in chain reaction.
Maybe they're something sort of new objects in Antibirth, but there's no description for them yet, even their name.
I don't know if it is suitable to add a note about this in both Mom's Bracelet and Objects' pages...
