For more information: in our league the races are Monday, Tuesday, Wednesday and Thursday. I changed the time and unconfigured all. Today we will have two races and the calendar changed to Saturday, Sunday, Monday and Tuesday.

There were two races today (with 25min difference from the end of the first to the beginning of the second). I received several complaints from the participants, considering that it was not fair. We do planning and a bug can not jeopardize the commitment of all of us who waste time for our interest in the game. I would like to ask that our problem be solved as soon as possible, canceling today's races (17/02 - Germany and Hungary) and adjusting our calendar which are run on Mondays, Tuesdays, Wednesdays and Thursdays.

Thanks for the comprehension.
