No the house load as an instance, same as an group dungeon or solo quest instance.It's undoubtedly one of those unfixable problems due to the game engine being broken situations. Not even sure there's any point discussing these things any more.
With a quick forum search I've found 17 threads on this issue on the first few pages of search results. And this is just threads that focus on this specific issue. There's many posts that bring it up in other threads with more general topics.Actually I made the same thread before. But unfortunatly it looks like most people don't care about it.
Has there ever been an official response to this concern?
