So I started a new world testing 1.16.0-rc2 and after a while it doesn't want to load things properly such as dropping items when distroyed or picking up items dropped from, inventory, etc. Upon restarting the world I spawn into a void. Checking the Client.main shows Requested Channel not connected and looking at the server.main shows the GrowTree event is popping up as void and causing major issues if not THE issue. Modded or not it gives the same issue too.
