Home ported at Fremantle,but won't let me end patrol.
 

I've done one patrol out of Fremantle,but when I came back it wouldn't let me end patrol there. I don't know if I got transfered elsewhere or what and I forget where to look in the files to see where I'm supposed to be based at. I'm just hoping this isn't a bug,since my 4 patrols on the S-40 are the best I've ever had in an S boat,and I really need to end this patrol...blah.

I use RSRDC. There I usually get transferred from Fremantle to Brisbane.

What version of the game are you running? Later patches changed the icon for your home port from an upright anchor to an anchor that's tilted to the left. If your home port changes in the middle of a patrol, you have to go to the new one to end it, and that's what it sounds like happened to you.

I'm running 1.4. I'll check again and see which anchor is tilted. Thanks for the info.
