i get this bug from time to time, really frustrating when your opening patrol nets you 57000grt!


however, what i tend to do now, is take my boat out of the harbour, turn her round and head home, then go out straight away again.
this clears the first patrol (and thus the bug with 0 tonnage) and allows you to sneak in a quick Qualification on one of your chaps
i usually put it down as sea trials or naff engines or sommat in me logs!
love the Type II myself you know, plucky little boat, you really take a shine to em when your first out hitting with very limited torpedo stocks, lining up those shots carefully so as to not waste any precious torps.
when you get to a type VII you'll happily shoot off torps at the rate of knots (pardon the pun) cause you feel like your torpedo tubes are belt fed!
