This was a temporary problem a couple days ago, when Humble Bundle ran out of serial numbers (they are bad in lettings us know in adavance to get more). Since then we provided them with new serial numbers and were hoping these would last.

If this problem persists, please let us know which products are causing the error (the HB page should indicate) and we'll poke them with more serial numbers to add. As soon as they have added them, you should be able to retrieve your keys.

Here is the result of yesterday's live mapping session.

Here are the results of last night's mapping session.

Here's floorplan of Nauheim station that was the result of yesterday's mapping session.

Here's the map I used for our game on the weekend, as it resulted from two of the live mapping sessions and some extra work.
