I backed 58$ on kickstarter back in the days. This was a great decision.
I would say perfect, but for one thing; I was supposed to get a Massively stylish George Washington style powdered wig. I do have a “Grim Dawn KS Collector DLC” key with humble bundle, which was redeemed long ago. Still no wig 
Talk to Corey next to the gate to Devil’s Crossing prison
Oh wow, thanks. I never suspected. Now my day is complete, finally united with my wig!
I have exactly the same issue, but neither corey nor the knight have response-options for that. Also purchased back in kickstarter
Have you redeemed the extra key for it on Steam or GOG?
I see you have requested help in Missing content after payment.
Yes it got fixed already, ty. Well I actually know you from the TQ-Fanpage 
Im a german player too and a friend of Elfe, if the name isnt foreign to you
Pretty certain eis will know him since he’s well known from the old titanquest.net forum as well as being here for many years. Hasn’t posted for a couple of years here, but he still lurks.
