Sometimes, it happens that, after working correctly, vikhr decide to be dumb : after fiing, they go down, to crash on the roof.
I checked that my laser is on, I reset shkval, I take care of the laser countdown, nothing change. Tonight, I fired and rearm several time without problem, after my last rearming, I shot 2 vikhr on 2 different target, but at the third one, I had problem.
Impossible to fix it, except by changing of plane. And it is not the first time it happens...
