Playing a GWX3.0 patrol in Jan'42 in the Irish Sea, 7th flot out of St. N, I took down a small freighter with a Type II out of the stern tube, loaded the eternal torpedo into reserve and there it sat. The Tube 5 was grayed-out and I couldn't get it to load, with a full crew in both torpedo rooms, including an officer and at least two NCO's in each room.
I do have malfunctions and sabotage enabled in CMDR. :hmm:
