As @Celes wrote "All Bonus instances are normally only used for Internet Cafe Users in KR version and we use them only as "event instances". So they should not have normal entries."
So again WHY good bugs which somehow benefit's free to play game of all players got fixed immediately while BAD BUGS are not !?
Availability of Garden of Knowledge (bonus) in Server Wide Group list should be considered as BAD BUG according @Celes sentence above ... Why Inventory Sell is "Fixed" but that is not?
