Patrol objective still incomplete after 7 days
 

The conventional wisdom is that one need only stay within a 100nm radius of the objective star for 48 hours cumulative to satisfy the completion objective. Personally, I've encountered a wait period as long as about 4 days before the star grayed out. But now I've been patrolling the Bismarck Sea for a week and the patrol objective is still listed as "incomplete". I'm out of torps, and the frequency of air patrols has increased. And to add insult to injury I've stumbled across an IJN TF headed for Rabaul, comprising 3 CVs, 2 BBs and various other ships, that I've had to pass up on as I'm out of ammo basically.
Looks like I'll have to RTB with an "incomplete" on my patrol logs, but I almost got caught by a Kate on patrol. Not worth endangering the sub and crew just waiting for the star to gray out.

What mod (if applicable) are you using, and do you remember anything specific of your orders? What is the approximate date?

Mods:
GFO 1.1
3000 yd bearing tool
CSL Deck Gun Optics Mod
Bigger Better Protractors
FJB Camera Mod for GFO 1.1
Webster's 300' Underwater Visibility for 1.5

Date is July 1943. Mission given at start of patrol was to land supplies on the northern coast of New Guinea; upon completion I requested new orders whereupon I was tasked to patrol the Bismarck Sea; objective star is located somewhere between New Britain and New Ireland.

Entered patrol area (100nm radius from star) on 17 July 1943, exited 23 Jul without completing the task.

jumping in here.....
in GFO the two Patrol Bismarck Sea missions have a 100 km patrol area, not 100 miles. yes, some missions are like that.
pulling out my handy-dandy USN calculator, 100 km is the equivalent of 54 nautical miles.
so, if you still have your mission-save files and can return to the scene, draw a 54 nm circle and hide in there for 48 hours and your mission objective should be completed.
good luck, Herr Kaleun!

I think I am correct in assuming that the "star" you are referring to looks like this:

Since in the Stock game, which GFO basically is, with some important fixes applied, only has the one mission area between New Ireland and New Britain. When looking at that particular mission in the Mission Editor, it looks like this:

(well, after merging the Campaign_NMS and Campaign_LOC it does - anyway...)
The assignment you got for this came from the DynamicMiss.cfg file, and that has the same mission effective dates as the PatrolObjectives.cfg file, which are from 19420801 to 19440301, so you fall within those parameters. The actual "time" for that patrol is for 2880 minutes continuous, which equates to 48 hours, or 2 days. But it is "continuous", which means that if you leave the "zone" (that "circle" above), the time then starts over. The Objective and all parameters appear to be valid, and I did run a test mission with it, and it does complete. However, notice that the patrol zone (circle) is 100 kilometers in radius, not 100 nautical miles. The 100 kilometers in radius equates to just under 54 nautical miles. More like 53.99+nm, which is rather small in radius, hence the two day time frame (most likely).

What some folks do when doing some missions, is they will go to the star, and "camp-out" there for the duration, just to make certain their orders fulfill, then go do what they want. Another thing to remember about GFO (Stock), is that you only earn 200 renown points for this particular mission Objective, so sinking a large merchant, or a light cruiser (enemy, of course) will earn you that with one or two torps. You ain't missing much dropping it and heading for home. Next time you fone home and get an assignment, it will usually be documented on the radio, so you should be able to go back through the radio log and at least see some of the constraints imposed by your orders. The stock game does often fail to tell you how big of a Patrol Zone you are dealing with though, but suffice to say that if you draw a 50nm radius circle, which would be 100nm in diameter, you should be OK. :salute:

Thanks guys. I loaded an old save and can confirm that 48 hours within a 50nm radius did the trick.

KM beat me to it, 'cause he didn't waste time with arts & crafts and show & tell... :har:

Love your explanation of why it didn't work, Propbeanie!

Happy Thanksgiving everyone!
