I suggest you change the advancement name 'Atarnative Transport' to 'Altar-native Transport', to make it clear that it's a pun.
So far, without fail, every time I've seen the advancement, I've thought 'That's an error, I should report that', and in fact only recently made the connection between the Runic Altar and the name of the advancement.

Yes, clarity is good. Expect to see it in the next version. Thank you!
