Both prosody and ejabberd MUC implementations now mark PMs with an <x http://jabber.org/protocol/muc#user> element, and the respective carbon implementations filter away duplicates, which is good. Unfortunately, this logic also affects MUC invitations, as these also have the same <x> element. However, invitations should be delivered to all clients. Therefore, if you are implementing an XMPP server with carbons support, please fix your MUC PM suppression logic.
