Yesterday I was working on something involving cloning clothing objects from ServerStorage to Workspace. After they were cloned, I changed the ShirtTemplate/PantsTemplate to valid IDs. If done on the server the property change is not replicated to the clients, and if done by a client it’s not replicated to other clients and the server. I singled out Cloned objects because if a new Clothing object is inserted and the ID is changed, the change replicates just fine.
A simple way to replicate this issue is to put a model with a humanoid, Shirt or pants into ServerStorage, have a script that clones the item, and parents it into workspace, then start a server and a player, change the ShirtTemplate on the server, and check for the change on the client.

This happens with both FilteringEnabled and without it.
