the manual had answers for you before this post...
there's a checkbox somewhere that will stop the game world from 'playing' while you play a game... see manual for location i don't remember -- pre-game or in the settings somewhere where every other setting is located
again, league settings page will have an option to reset stats.. if not visible, click available actions - under 'functions' or 'league functions'
you could go search and read for an answer, or wait 7 days for someone to hold your hand and type out the answer... upto you in future. you can take control or wait for help.
