Yes, it appears to be a bug. We will fix it in the next update.
In version 0.5, it is not possible to give the stone to Shu. Completing the quest with Shu is only available in the paid version.
Awesome! Glad to help! Also, I'll apologize for misreading the updates. I thought I saw the Shu stuff in the version 0.5. My bad haha
This is our mistake in the numbers in the versions.))
