Playing the instant mission "anti-ship" on latest beta. This is how i reproduced it. Tried all settings in "ctrl" i.e. popup, skim, eff,cc.
1. Set 802Ak to LOS mode
2. Fly within ~20-25 miles of the ship at any height and launch. Instant despawn.
Also in LOS mode the missiles will explode after a short while when not within the 20ish miles or will fly to about 35-40k.
