i think DarkMaster he working on new project if im not sure , or maybe Season 4 next update
for the game crash , i have no idea what is , try to disable events or command , and check the game log.
But for me there one problems is , When move to Crywolf or server 19 , and warp back you will get DC and after join back again the acc still connected , if you keep press enter again and again , hole game server will get disconnect , but not crash , So when player click on server list,Its stuck on login window.
For people who are have problems with box of kundun +1+2+3+4+5 drop same items
try to get other EventItemBag files from other muserver file than it will be OK.
