Oh, I thought you meant only the shulkers were affected now. Could you split off shulker entities from this ticket? They're not a block and thus should be handled separately.
If shulkers are affected, boats are probably too, by the way.
migrated
Yeah will do, just have a question.
Does this apply to both Open Shulker Boxes and the Shulker Mob?
And boats are affected aswell as I have stated. Whether it is occupied or not, mobs dont see them as an obstruction in their path.

New ticket created for the shulkers/entities MC-181580

Shulker boxes are blocks, not entities, so they should probably be included here.

This is s till not fixed in 20w20a. Flowerpots must be included aswell in this list. Usually mobs get stuck on these blocks
migrated
@Dorgami Flowerpots have been fixed in MC-96319, mobs no longer gets stuck in them nor think they can pathfind through them. The list above are the few remaining blocks in the game mobs still try to pathfind through.

Both types of Camfires (lit or unlit) does no longer seem to be a problem. If somebody please can verify this, then I will cross them off the list.
