This is a part of a diving report from last night:
...when launching my last subrocs with a run to enable of 1 nm, they just kept flying until they run out of fuel. One even went straight to the sea, not releasing its torp.
This happened to my last 4 subrocs in a combat dive, launched from 150 feet/depth. They just ran straight, except for one going to the sea floor. Not one released its torp. Possible bug?
