New bug, one of my Worlds will not load when I select it, it says that it was loaded in a newer version, the last version was the last or the second to last beta version.

1.17.10.20 Beta and 1.17.10.21 Beta are higher versions than 1.17.0. You will need to wait until 1.17.10 releases to load your world again.

I'm now on 1.17.2 the latest release, and still getting the same thing saying that it was loaded in a newer version.

1.17.2 is still a lower version than 1.17.10.

So unless there's 11 updates to 1.17 I won't be able to play my world until 1.18.

🤔

There will not be 11 updates to 1.17 and you will not need to wait until 1.18 to play on your world. The betas for 1.17.10 have recently ended, so it shouldn't be very long until 1.17.10 is fully released.
