V12. Air combat. Crash when two planes both intercept at same time

Launched two interceptors against the same small UFO. Both reached it. The game showed one interception screen, but the music was doubled, as if both were active. When the UFO crashed, I got an interceptor screen saying "signal lost" and the game crashed to desktop.

Can you please attach a save game about this issue?

I had something similar - two interceptors in the same group attacked a fighter, music doubled. The game continued a short time after (I got a research pop up), but soon became unresponsive.

Yep. Had the same just now. Was going to report but as it's already been done. CTD'd as soon as my half-destroyed F17 hit the edge of the screen.

At what speed did you set the game when you were intercepting?

I've had this issue when I order my planes to an ufo, then switch the game to full speed. Other speeds didn't give me issues.
