Hill giants will drop "Nothing" most of the time
What I did: Killing hill giants in edgeville dungeon.
What I expected to happen: Receive normal drops.
What actually happened: Most of them only dropped bones and charms. It appears that "nothing" weight is set to 1400.0 in the drop table: https://gitlab.com/2009scape/2009scape/-/blob/master/Server/data/configs/drop_tables.json#L7271
Sources: 2009 data from the wiki lists several "very common" and "common" drops: https://runescape.wiki/w/Hill_giant?oldid=1573995 , while with the current settings the most probable drop is a 1/46.48 chance (so no common/green drops at all). According to the OSRS wiki, nothing rate should be 1/128. I imagine that setting it to that should fix the rest of the droprates.
