"False Advertising"

I was playing a game of Imperial Era today, and as I always do, I checked the units to see where I should go, and what Strategy I should use. Since I saw that there were Air units , I used Sky Menace and picked Russia. Although I was a bit confused, I understood that there are a ton of imperial games, and I thought I remembered one having air units. However, when I got in game, the units were not offered, and when I checked the units list again, it was said that I had not unlocked them yet. Although this isn't the largest bug, I think that every game that was created prior to AtWar, that had unit retrictions, shows the units that they have restricted, without them actually being available. If something could be done about this, I'm sure it would end a lot of confusion.
