Custom channel Guardian spontaneously reset me to operator (so far as we know), and bounced the guy who is SUPPOSED to be the operator. So far we've not been able to pass the star back. I've tried both the graphic interface, and the old /chan_user_mode <channel name> <username> +operator.
Not really a bug, more an implementation detail.
When you /chanjoin a channel that doesn't exist, Paragon Chat automatically creates the corresponding XMPP chatroom. It uses the room configuration interface to request that this room be created as
non-persistent. That means when the last person leaves the room, the room ceases to exist and no longer retains information about who originally created it.
This is by design, as otherwise every time somebody typed /chanjoin on a lark, a permanent chatroom would be created that would hang around forever, even if the owner immediately left the room. That's due to some quirks of how XMPP handles room ownership that make it impossible to duplicate the traditional COH behavior exactly.
It is not implemented yet, but the current plan is for Paragon Chat to convert the temporary room into a persistent room the first time you do something substantial to the channel, such as promoting someone else to operator status or setting the room to private.
For now, if you want the channel to stick around and retain its ownership and moderator list, you'll need to create the chatroom using a standard XMPP client and then join it from Paragon Chat using /chanjoin.
