Sending messages to the server doesn't seem to be working in the reverted build. I simply host a server by using the OINC host function in MMF and then have a client join and try to send the server a message. No success.
Then there's peer messaging. I'm not sure if this is the correct way to do it, but lets say you want to send a message to a specific peer. I select the peer with the 'select peer by id' action and then send a number, without success.
