fuck you. just fuck you

You do realize that this is a beta correct? GGG is opening the game to players right now specifically so that they can find out about these bugs and fix them. By entering into this beta you have graciously (or not) volunteered to go and play the game as it is with the understanding that it will be unstable and buggy. I would hope that you have submitted a bug report so that they can address the issue that you have.

I also hope, that as a coder you understand that one man's bug is another man's feature. While you may dislike the fact that you travel to town upon exiting the game, many other players use this as a feature to easily and quickly return to town without using a town portal.

Not to mention the fact that clearing the data for instances after players quit the game is efficient since most of the time those players do not go back to those instances. As far as programming goes, that is a perfectly valid choice which is especially paying off now that their servers are being slammed by a much larger than expected crowd of people.

That said, you do have a valid point in that GGG could have made a choice to retain instance data across sessions and remove it after the standard 8-15 minutes. However that really should go in the suggestions thread and rather out of place here.
