Yes because some changes for clients listening on multiple network adapters were rolled back till we could test more, as it was breaking things for many.

Now the game will use the network adapter issued by the OS for the client, which will be your default one. You can change the priority of the adapter in network settings.

Another option get the local ip issued by the hamachi adapter. Then go into the game setting.xml file, change (or add) a new field called LocalIpAdress which is that IP. You only need to do this for the clients. This will force the clients to connect via the hamachi network
