Custom mob head not updating immediately

[Mathias]

When I set the owner of a mob head with SetOwner, using the function DoWithMobHeadAt, the skin of the head only changes after reconnecting to the server. Can I change this behaviour in any way?

Setting the owner doesn't re-send the metadata to the client. We should add a m_IsMetadataDirty flag to entities and all the Set functions should set it; upon ticking the entity, if the flag is set, the entity should re-send its metadata to the client and reset the flag.

Come to think of it, I'm not sure if the protocol supports re-sending the entity metadata, though. It might be that the metadata is sent only with the "create entity" packet, so we'd have to effectively destroy and recreate the entity.
