Clean install, everything working nice-and-neat. Started pre-war, ran 6 patrols and was transferred to a training cadre. Started with a new Captain (using SH3Commander) and again everything fine. It's mid-March, 1940, and in grid AN, I encounter a small convoy of three ships lead by an armed trawler, all Holland-flagged.
Heading to intercept for a stop-and-search, at approximately 6-7 klicks the armed trawler turns to face me and begins firing.

I'd really like to know what, if anything, is/was the culprit. I can't be exactly sure, but it seemed as if the last hit I'd landed had mortally wounded the armed trawler, and SHIII CTD the moment the trawler "died".
