A 게임 세계 can be permanently closed at the end of a season if it has one or less managers and it is administered by the SMFA. If a 게임 세계 is due to be closed then a warning message will be displayed within My Home.
However, to prevent this from happening the 커스텀 게임 월드 owner needs to reclaim the 게임 세계 or alternatively it needs to be purchased as a pre-owned 커스텀 게임 월드 no later than the last Turn of the season.
