Back in late October and early November, you may (or may not) remember that Blizzard was having some substantial issues with their character transfer system. To prepare for the release of Wrath of the Lich King, there was an epic number of people moving characters around for one reason or another. A problem came up where some characters were getting lost in limbo along the way. Stuck, and unable to be played.
One of our readers wrote in this morning with a followup, and it seems that everyone who had issues is being granted a 15-day playtime credit on their account to make up for it. Half a month across the board is a pretty substantial credit, especially considering many of the people we've heard from were only locked out of their characters for a couple of days. I'm sure we'd all prefer there was never a problem to begin with, but this is a pretty generous compensation if true. I was impressed when they gave everyone a three day credit awhile back.
