1.7 snapshots and zombified piglins don't drop gold ingots,gold nuggets,rotton flesh, Blaze not dropping blaze rods, squids not dropping ink sacks and potentially more mob loot not dropping.
i do have a data pack that makes it that mobs have a chance to drop their heads so that might be the problem

Yep, that's definitely the issue (datapack formats have changed in 20w46a). If you disable your pack, that should fix the problem. 🙂
See MC-205130.
cannot reproduce, try removing your data pack and see if that fixes the issue
