One tactic i tried tonight and that seemed to work was to engage a convoy and sink the escorts. Then I surfaced and called in the convoy! I got the order to treat tankers as a priority - and then had a field day
. Ever since the 1.3 update I have not felt safe in approaching a convoy surfaced as the escorts are now just too good at spotting me before I have the three ships in sight necessary to send the contact report
.
