Was curious if the leaches were needed for sunken bones to spawn ive joined the test server I love the game but being as leaches arent in the game I had theorized that leaches were hence required for the sunken bones to spawn if so I understand was just looking to see if it was a glitch or intended

In the deepest areas of the pond, sunken bones are just lying about. Try looking around the t-rex toy's legs. You need the acorn shovel to pick it up.

I am sure the op knew this and did as I have and collected all the bones in that area. For me that was several game days ago and none have re-spawned.  I was able to collect enough to craft the diving helm and bone dagger but can no longer find any more bones to craft the trident.

Same thing for me. Bones are not respawning. its been at least 6 ingame days (probably more). only the scales seem to respawn.

for me both are not spawnig back, but my Koi Fish is also gone from my pond 😄 .

He is flying away to the moon 😄 and did not come back after resetting all creatures in the save game
