Bones Update 1.2.4

Fixed a server-side issue that makes the mod not launchable.

For incoming versions 1.21.3 to 1.21.8, the content (mobs, items, blocks...) of Bones Update 1.2.4 is the same as the v1.2.3

Can I use the version of Bones Update 1.2.3?

Yes, if you are playing on singleplayer on your computer, without a host server.
