Mainly I was testing Dredgers v2.4.2 OXP hack I was working on, but even with regular missiles (and without that OXP) I've seen it happen where alternating through targets doesn't allow the missiles to lock and fire.
My HUD says I have missile locks -- they just refuse to fire.
On Win XP SP3, 1 GB ram, ATI Radeon 9600 vid card with 64 MB DDR.
Oolite v1.74.1 missile/s not firing.
