What the hell - one of my LBAS slots just lost ALL proficiency on 6-4 without suffering very severe plane losses at all. Only 4 planes lost of 18, but proficiency went from double chevron to ''nothing. ''And the other two bomber slots lost 8 of 18 and lost one level at most.

Anyone ever see something like that?
