Missile ships with PD

[Taera]

In my latest game i've noticed an interesting thing.
My poor TechnoLogic AI is not programmed well enough, so it has Cruisers (!) with lvl.5 DUC, lvl.2 PDC and lvl.1 CSM. Now it was fighting the Pyrochette (both were AI).
When i;ve turned the control to myself to see whats up i've noticed an interesting thing.

Enemy ships were all using lvl.5 CSM. Now there are three attack ship designs in the list - two with lvl.1 CSM and one with planetary napalm ( <- i realy like that thing). Now when i tested the designs against the enemy in the simulator i've noticed an interesting thing.

When my ships did not have any seekers on them, the AI played nice - shoot their missiles and ran away from my fire range. BUT!
When i tested the ships with lvl.1 CSM i've noticed a strange occurence.
Enemy was on DEFENSE place. So he fired first. Then my ships fired their pathetic missiles.
THE FIRST ENEMY SHIP TO TAKE TURN WENT TOWARD MY SHIPS JUST TO SHOOT THE MISSILE! it was dead after that. Two others died the same way.

now is that a glitch or what?
