my beds and heads are buggy, my sheep became chairs after the new update

Looks like a resource pack model error.

Do you have any resource packs applied and if so, please try removing them all and see if the issue persists.

Commenting back will reopen the report.

the only package I had was music for the junkebox, I disabled it and it remains the same

Please check if the world itself has any packs applied as well.

Thank you for your report!
