the issue was continuity, i found a old issue on the minecraft forums which someone had a silmar issue

No, the issue is that you were missing Indium. Continuity is fine.

This is the wrong place for support requests. The correct place is the player-support channel of the Discord server or the player support category on GitHub Discussions
