Once again asking for Anenemies and Fossils to have a small chance to drop.

[This14Real]

My world is so old and I made the mistake of retrofitting when the Anenemy update was live so I only ever got the small Lunar Island and 5 total Anenemies. This was later fixed to spawn a lot more but the damage was already done. 
New worlds can have up to 30+ Anenemies with the addition of the small lunar islands around the big one.
Please let us have a chance to drop Anenemies from Sunken Chest, I don’t care how small of a chance, even 1%.

Also Fossils have been nerfed tremendously with how big the spacing from each fossil is, diminishing its practical use now only for summoning Ancient Fuelweaver or used as decoration. Can we have Bone Helm and Bone Armor be deconstructed to drop 1 Fossil each?
Once you have a couple of those armor pieces all other subsequent drops are useless and tend to pile up or thrown away, at least Fossils can be used to decorate.
