Same here. No update on Groupees, no keys in my bundle. Go to Steam, says I have to come here. Come here...no key. What's up? In the over 250 Greenlighted games I've bought through bundles over the past few years, I've never had to chase a key down like this.
EDIT: I posted a more polite version of this in the Steam Militia forum immediately after I posted here. Within half an hour, I received a key. I rarely see a developer this active, this fast, and this dedicated to a game so long after its release. His games are now insta-buys from me.
