Computer virus + allegiance suberter

[CW]

Sometimes I really wonder if the SEIV combat AI was intentionally programmed to spoil your plans!

I've just designed an almighty battlecruiser armed with 2x computer virus III and 2x subverters III. I also threw in a talisman to make it absolutely lethal (ok I admit you usually don't get to do that without a max tech start, I'm just day dreaming! ). Anyway, I arranged the weaps such that there is a virus followed by a subverter, then another virus and another subverter. I threw it into the simulator fully expecting that the ship would take out the two unarmed, MC-equiped large transports in the first salvo. What actually happened was totally unexpected and absolutely frustrating... that's why I'm here. The ship always fired BOTH viruses at the first target, even though only one was ever needed to destroyed the MC. It then had to wait for three turns before taking out the second transport!!! Is there a work-around out there? This is a very serious bug in my opinion.
