I found nothing like this in the setting.
So please make me an screen an show me where this option should be.
I have in only:
General: Music, Sound, Language, Screenshot, FHQ and Contacts
Game: Fullscreen, Multicraft, Party selection, Chat alerts, Energie refill question
Accounts: Facebook, etc.
Notifications: Crafting, Quest, Trade, Upgrade, Arena and Daily quest
So in my case is no way to safe me/other for such mistakes.
And I have never played a game where you not get ask befor you change anything like this, first time here.
I see only 2 way to solve this, first confirmation message (if you click ok without reading your fault) or second delet the 10 day rules for 1-3 change per month (and whit this, I think you would have many city jumper). So first would be the best to prevent mistakes like this.
I behave myself? As child, I see Tazan naked, Pinocchio was an liar and Aladin an thief. Cinderella come home at midnigth. Snowwhite lived whit 7 men. Popeye was an smoker and tattooed, Pacman take an pill after pill. Happend in my childhood.
