This is the workaround I am using: https://youtu.be/utbKAN_hGxw?si=1a2msuieNjCvOIzu
I should mention that I’m on PS5.
I’m having the same issue, except with pistons instead of purpur stairs. Purpur stairs and all other blocks sort perfectly, but pistons do not sort. Even other items in the same chest as the pistons sort correctly. Copper golem opens the chest with pistons, but shakes his head as though none were found.
Update: This issue is happening with every world when I try a resource pack. It will no longer play unless there is some resource packs activated. I think it might be the ‘remove resource pack’ button which is broken. It is not actually removing the resource pack, despite appearing to do so.
