@NetherNinja @Mega_Spud Uh oh! Can you file it on http://bugs.mojang.com please? If you can attach your world file or just the gamertag and name of the Realm, we can make it happen on our end and find out why it's broken. Thanks!
@NetherNinja @Mega_Spud No worries, if you can file a bug with the gamertag of the owner (NetherNinjaMC?) and the name of the Realm, we can pull it up.
@EricStepanek Hmm, there shouldn't have been any render distance changes from 1.17. Could you please open a bug on http://bugs.mojang.com with the details of which device you're playing on?
