Summary:

UI text fields on UI screens prevent the player from leaving them blank by making the button to proceed to a UI page or something unclickable but it can be bypassed

Steps to reproduce:

1. On the main menu go to multiplayer
2. Go to direct connect
3. if you find any characters on the text field then remove them and make sure the button which lets you proceed becomes uncklickable
4. press the enter key

Note: This also works with the world creation UI screen with the world name text field

What happens: The game proceeds like normal in the world creation screen but in multiplayer it gives an error since there is no ip address typed in.

Expected results: When the text field that requires the player to put in characters is left blank the enter key shouldn't work
