Thanks for making an account just to let me know! I really appreciate it!
Ah sorry you got one of our known bugs in the web build. I posted a dev log today with a bit more info about them. Basically for now if you leave that stuck bone behind it will respawn in another location so you can still get it somewhere else.
Haha you also shouldnt be able to see the sky there but that'll be fixed in the next build too 😅 sorry about the bugs!
Currently the fossil quality is random and you can pick up better quality bones over time that will swap out. Also if you hit the bones when excavating them it lowers the quality. Do you think it's unclear the way it is now? Let me know if you think we need to explain this to the player or change how it works? thanks for playing and I hope you'll come back and test out the next update, we have lots more content coming 😉
