Maybe a general solution would be to delay switching disposable until the fired ammo becomes null
Although that might give time to "reload" which we want to avoid

We may want to just handle the weapon switching in ace_missile_guidance

Yeah I did a PR for basically that, though it isn't weapon switching per se. I'm not sure if any other seeker types need the same fix, though.
