[BUG] Dodgers Make You Autofill
The Bug If you are in queue and somebody dodges and it puts you back in queue it is moderately likely that it will autofill you in an unselected roll.
More Detail My MMR is probably about Silver/Gold so I should have lots of players to queue against. Whenever I queue I very often get my primary role and sometimes a secondary role and I never get autofilled to an unselected roll during my 1st champ select. However, if I am in queue and somebody dodges... then I am moderately likely to get autofilled in an unselected role during the 2nd champ select. What I speculate is happening is that when somebody dodges (especially if this happens more than once) the queue system determines that you have been in queue very long time and compensates by immediately finding you a position... any position... even if it's an autofill.
It's to the point that in order to work around this bug if somebody dodges I completely cancel champ select and then re enter queue to restart the internal timer to prevent being autofilled.
