While in the pond depths when you dig up a sunken bone it starts to glitch and you can’t pick it up.

I have noticed this bug also and cant believe there's only this one post.  The bone will start to rise like its floating up but will glitch back down to the ground and try to rise again.  

And even if you try to pick it up when the prompt shows on  screen, it wont let you grab the item.  It doesn't react and keeps glitching.

Luckily I have found a reliable way to pick the item up easily. If you try to grab it right as it goes off screen out of view, you will still be in the right position to grab it and it will actually let you take the bone. The timing isn't too difficult so it has taken the hassle out of it.  

But still this is a very annoying glitch.

We have noticed this bug partly. When I was hosting the game, my friend had this issue, but not me.

still having issues with this, sunken bones can't be grab/nab. it appears they are like floating in glitch. hope you can fix this ASAP. as it is very frustrating. i still need to ask the game host to pick it up for me.
