Ahoy Fleet,
I've also tested this in various destroyers and haven't noticed anything wrong with the torpedo spread angles.
Try doing a check and repair of the client to see if any game files were incomplete or damaged during installation of the update.
If you're still experiencing the same behavior, create a WGcheck report and send it over to the Support team for review.
You might also want to attach a clip of the replay so the Support team can have context of the behavior.
