As for your #1 question, there is no way to make a grid overlay when a modder is building a mission, so will have to actually start the game and attempt to find the center of a patrol grid and either the actual longitude and latitude, or the decimal system, and then translate that into the mis / tsr file for the mission. Each mission built goes through that process. All that said, my guess is that you have a Type II boat, and are assigned to be off the Shetlands. Do the orders actually say something like "Specific opera Grid Square AN5159 remain on station 96 hours within 75km"? Use where the star is, as opposed to the AN5159, and you should complete just fine. That looks to be the only one that is "off" for the AN51 assignments. There are others in the game (not many), and some of them are the grid system's problem, other are the placement of the patrol circles. I'll see if we can't get Fifi a few files in a few weeks. For now though, I'm busy with a couple of other things in FotRSU...

- I'll also try to get the English versions of the tsr files for the ContactReport missions in the DynamicMiss folder to him...
