First off, let me just say that having quests that are required in order to progress to the next area is a very large design flaw. But having those same REQUIRED quests bugged at various steps for various players is down right unacceptable.
I avoided every single quest that I could leveling from 1-50 because I had already experienced the utter cluster that phasing, mobs that won't spawn, interactive's that aren't interact-able, and the various other bugs that just about every quest is riddled with. So yes I have to quest through VR content because I am forced to, to reach all the VR area's.
And NOW my main story quest in Reapers March is blocked for the past two days at "The First Step" quest because I cannot drink the Moon Sugar Elixir as it is not interact-able for me.
And I am not the only person this is happening too.
You all need to get the main story quests working before making them REQUIRED to progress, it would save yourselves and your customers a lot of frustration.
