I have just started the German campaign 1st Patrol 3rd Mission where I have to sink 7000 tons in LZ 12 and I have been patrolling LZ 12 for 4 hours (actual time) with no ships in sight! If I continue any longer I'll end up an old man for real!
Considering the fact that these U-Bout missions were just created by Ubisoft from a 6 years ago gaming engine, is this a known problem?
Edited: Problem solved
