Is there any way to delete the Neighborhood Brawl popup holiday permanently? I find it ridiculous that there would be a holiday where it's encouraged to get into fights. You have to get into a lot of fights to complete it too. And while it doesn't damage friendships, it does damage Reputation.
So you can cancel it, if it's scheduled for later that week. But I don't look at the calendar all that often, and usually I find out that it's today- too late to cancel. And when you do cancel ahead of time, this is one that will pop up again, because it's not a regular annual holiday.
