Could we get an actual explanation as to why the queue can't be used?

[seebs]

the queue is what's making the server crash. I would think it would be the logical reason...

How can a queue make a server crash?

// It is inconceivable that more than 100 players would be in queue. This would indicate a programming error, most likely.
if (queue.remainingplayers() > 105) abort();
