Due to a bug, arena size for new Utopia teams has been mistakenly set to new arena sizes announced in season 33 news post. All Utopia teams created after about January 9th were affected and have had an unfair advantage over other Utopia teams. This has now been fixed and their arenas have been reduced by the proper amounts.
Those teams have indeed played a lot of games in the meantime with the bigger arenas but due to the fact that recalculation of correct attendances is now impossible and the fact that these teams are indeed new and not a big threat to the power rankings in Utopia, it has been decided to let them keep the additional income (if any) they have received in the meantime. After all, it was our mistake that allowed this.
From now on, new teams in Utopia start with old (original) arena size numbers. Sorry for the inconvenience.
