Well I've had it for several days now (or weeks maybe idk), and it has produced over a hundred F111 aircraft fighters, but every time I battle I don't see it in the battle details. My guess was that the F111 isn't certified to be used at my (or my opponents') level, though I'm currently at level 149.
The bug is here: how come the aircraft factory is unlocked at a lower level than what it produces?
and at what level would I be able to use the F111's?
