There has been improvements where after it says Unable to Connect, it starts by saying generating world and resources then Done! But the it kicks me back to the main menu. 

The Error Code:[json][error]-Could not parse metafile json file hat_conductor.metafile.json

The Multiplayer goes in first, the the Unable to Connect screen, then after continuing it says generating world and resources than done! Then it kicks me back to the main menu with same error code. 

Hope you guys can figure out why it kicks me back to the main menu and why that error shows up
