A few bugs I encountered :

After returning to editor after testing a map where the player's death is inevitable, sounds continue to play. (death and bell sound effects) It's as if you're still able to play your map while in editing mode.

Going to tribe house via tribe interface while in edit mode causes player to get locked into edit mode. Restarting client/browser is only option.

Exiting map editor via any interface while in validating mode causes the "back to editor" button to remain where it was while in map editor. Clicking on it removes it.

Exiting map editor is possible with tribe interface (excluding while in edit mode), the menu and training. Yet it is not possible to exit with friend's list or with chat.

Note - I should have been more specific with titling this thread. If possible rename it 'Map Editor Sounds / Interaction w/ Other Interfaces' or something more appropriate.

Those bugs just happened to me.
