Found 1 major bug and two big ones:
1. Secret Melody main quest loops. You are told to go to speak to Scout Ranger Fugus, but when you talk to him he tells you to go to talk to the guild master. When you go to the guild master he tells you to get back to Fugus. It seems a trigger is missing in the Fugus' part of the quest. This is a HUGE bug, because it doesn't permit the warrior to continue the main quest.
2. Cannot join arena channel, and thus not able to continue the "Colosseum Victory Records" quest.
3. Cannot get some quests in Cadillac Village, even if I didn't do them yet and they have a lower level requiement than the one I am at.
Plus, there is something wrong with the drop rate: I am not able to get any of the veteran mercenary stuff from the dungeons, while I was able to find them in the SEA version.
And there is something that shouldn't be there: white and green (D and C tier) items require agate fragments to be enchanced, something that wasn't in the SEA beta, and it shouldn't be in a private server either.
