skeletonbow: No idea, but I'd bet that it is probably some kind of World War II related game and it's probably over Nazi symbolism in a game likely. Um... what about Sniper Elite Berlin 1945? Or the Blitzkrieg games? I'm sure there are more possibilities...
They didn't remove another game or lock it for Germany. Before the sale started the counter was 960 (in Germany, 962 in most other countries).
Train Fever was already included, because it had a catalogue entry in the upcoming section. Then they added 5 games from Nordic for the sale (965) and the new
Sokobond (966). When the seasoned deals were over they removed the five Nordic games again and now the counter is at 961.
Everything's fine, no game removed, no need to worry.
