So far I did not have a function that would end a trivia game in case the quiz master would not ask all the questions. The game would be open and nobody had the chance to start another game.
I now changed that. In case someone tries to start a new game and there is one still open, and the quiz master of the open game is not online, the old game will be automatically closed, the winnings distributed and a new game is started by the new quiz master.
So if the quiz master is still online, please ask him/her to continue the quiz or to close it by skipping the remaining questions.
