I have the same issues with the same ball and scrying stone, ever since the launch of omu I have been seeing more and bugs in the game which is unfair to the people cause they can't get there achievements and arc doesn't seem to care.
I have been hunting 4 a eotyrannus talon, I have killed at least 90 deinonychus the Eotyrannus only showed up 3 times no talon and spent 4hrs doing it the rare creatures in chult and omu have a very bad drop rate and amount of times that they show up, there worse then enchanted boxes at least with them you guaranteed…
there is a specific sahha ball that I cannot interact with so I cannot get the achievement Jungle sahha I have taken a screenshot of the ball that I cannot interact with. I have tried defeating myself, logging in and out and other characters but I still cannot interact with it. Is there a bug or glitch in the game?
