Event Problem

I'm asmo, kinda "new" to the server (been away for 4 years).
I deleted my old characters and have been struggling to find out about events and stuff. Yeah, I've read the guide made by that guy (forgot his name) and it was very helpful. (thank you, stranger!)
The point is, I've created an elyo character then changed to asmo and that MIXFIGHT event where you must find boxes, is it bugged for asmos? Cause I've been there with my brother 6 times I think and found nothing. As an elyo I've found so many boxes and that is kind of a hype breaker you know?
Oh, and my brother has a bug with group (he can't invite, leave nor post group offers). - He managed to leave it somehow it worked by jumping on a "infinity hole"

 

The mixfight with the name of maps...ex>mixfight(altgart)are those who have box's,the others with numbers like 3 daevas or 6 daevas,dont have at all.About the bug...just w8 all menbers loggout and the party will be dismiss,and about post offer,it may be your item.pack,about be invited...i really dont know

 

Enter Mixfight is there are names of the map like: MIXFIGHT [Verteron], MIXFIGHT [Altgard] - There you can farm those Bastion Boxes for free. But also BEWARE, there are people entering inside just for trolling (killing you for fun).

As for the group bug: Just try to enter any rift (Just not the Hyperion or you'll end DEAD). Either 1v1 Training Rift, FFA , or Mixfight again.
In 1v1 Training and FFA Battlegrounds, it automatically disbands the group you're in. As for the Mixfight, you have to enter and leave the area again with a Sanctum/Pandaemonium Scroll.

 

Oh, thank you guys.
He managed to unbug somehow cause nothing was being possible like entering dungeons, etc. Not even logging out was doing something, anyway.
One last question, what does VGO means?

 

VGO: Very Good Offer
