First time I marked drop zone few hexes from map border and Ju88A-1 showed up probably too close. It said that he's targeting KV-1, but when he was over him he turned and was gone. Maybe he needs to be further when targeting, or he can not attack? But that would mean that there is nothing outside of the map.

Second time I have found some fortifications, and set drop zone on them (this time in middle of the map). But when Ju88A-4 was over them he noticed a bunker three hexes to the north and changed direction. Same as before, he did nothing (except for spotting that bunker).
OK, I can understand that for some reasons bomber can't drop cargo. But after that they get 1 damage, and can not be used again. Shouldn't they be available if they have bombs and no real damage?
And once again the computer mixed something up and I saw all of my enemy's units. Anyone else have this problem (so far I have seen it only in hotseat)?
