A brief follow up on this "tour"....
After reaching my assigned patrol area and spending the required amount of time there, submerging at dawn surfacing at dusk (rumors were spreading that the captain was becoming a vampire but thats another story). We came accross a grand total of nothing. We then got the mission complete.
I was supprised when we recieved no further orders so we headed back to Brisbane which is where we launched from. We ran surfaced alot in order to make good time but were constantly harrased by air patrols. We did stumble into one of the biggest convoys I have seen.
We attempted to set up an intercept course to make good use of our few remaining torpedoes and sure enough got picked up by one of DD's. Must have been one of those "eliete" fellows. To make a long story short we evaded worked around (for some reason the convoy stopped) got off our 4 shots and sank two merchants, and slipped away. Later surfaced and phoned it in.
Later on our trip "home" we ran accross another large convoy but being un armed we worked into a position away from the dd's surfaced and called it in. "Good find come on home" Pac wrote us back (while we were at 150 feet :hmm: ).
So we continued back to Brisbane with A few close calls from air attacks but we eventually stopped at a tender for fuel. We left the tender and sailed to Brisbane. Upon arriving at Brisbane we were supprised to find out we were denied docking privilages and could only refit.
Well... I delved into the "guts" of the savegame files to find out just where my home port is

and headed back to pearl. We planned to stop at Midway for fuel should be a quick trip at full ahead ! Nothing better to do so I checked my orders page.

What ! new orders ! "These bloody orders are 6 hours old !" (sorry I couldent resist). Orders read "Attack enemy shipping in the Marshall Islands"

Doh ! we just left there ! Were almost to Midway anyhow lets refit and sail back to the Marshells...
Okay out of charecter now... from what I gather the simulation "knew" I was out of ordinance and did not issue new orders untill I had some firepower back on board.
We had probably received the new orders after the first refit however it went un noticed amongst all the contact spam.
We will see if our luck continues..
