Just had this crop up last night.
Saved my game when I got the initial convoy report.
Prosecuted the contacts. Hit a med. cargo and Ceramic liner.
Dived ahead flank, launch decoy/turn. Escort goes directly overhead, pinging stops and... CTD.
Restarted my laptop, resumed saved game. Same as before. Instead of "Depth Charges In The Water!" I got a CTD.
Time to test my RAM.
