Well, maybe some of you might be interested to know iRO (Gravity USA) was and is having lots of "technical" problems recently and was forced to cancel all WOEs until further notice. Well lots of things went all wrong after their last maintenance on Tuesday when their Halloween Event was launched. Sprite error from new headgears causing chaos during WOE, NPC exploited as they were buggy and giving away free "Lucky Boxes" (normally you have to buy them with real cash/kafra points), lag spikes when Halloween monsters/NPCs were summoned (massive lags in general as well) and they were trying to improve WOE when some unintentional WOE changes were made - you can't memo in front of castle which frustrated alot of paying players.
Must be some big boo boo to cancel All WOEs until further notice. As an alternate, iRO is offering daily WOE on iRO Sakray (test server) instead.
