It was a brief glimmer of hope, LOL.
Spent
5 days within the 100nm radius before the patrol loc 'star' turned grey and mission was complete.
Returned to base and offered a new sub. I accepted sub (Balao) and was subsequently assigned to patrol................drum roll please.................HONSHU!!!!
Not only that but unbeknownst to myself I was relocated to Brisbane, no warning, no message, nothing, just BAM, I'm in Brisbane!!
God, I hope they fix these things in the next patch, if there is one!!!!
