Are there any known issues in the Portal Knights 0.8.0 update?

Here are the known issues for Portal Knights version 0.8.0 (Steam Early Access):

• Joining friends through the Steam client doesn’t work. Please use the in-game joining menu.
• Joining a host who is quitting the game at the same time can cause an endless black screen for the joining player. Please restart the game if this has happened.
• It is currently possible to join a friend who is playing with a host player who is not your own friend. The network code has been reworked as preparations for Split-Screen and “Players on different islands”. So new issues may occur due to this.
• Players leaving and joining are currently not mentioned by name in the alert popup.
• Changing the display mode from windowed to fullscreen can take two tries before it works correctly.
