upgraded to 4.11.1 and suddenly the B17 is an option in multiplayer?

[mind_crash]

as above. when I select a dogfight mission under multiplayer to create a lan server for me and the father suddenly I can see new aircraft...including ones that are clearly AI only... like the B17.....I can select it and click fly.....then when the map loads I am not at the runway and cannot see the craft......if I press F2 I can see it but of course cannot fly it...anyone one got any ideas to this? I have just go through all the standard multiplayer missions and they are the same....puts a real delay on me and my dad playing as I have to figure what aircraft I can actually pick....
