You will have to complete the jigsaw puzzle to get the final coords. Cache contains a log only so BYOP. On a country drive I spotted some interesting things. This is one of them.It would be wise to create a jigidi account and sign into the puzzle site to save your work. You can then pause and resume where you left off at any time as long as you are logged in . If you leave the site and are not logged in you will lose your progress and have to start all over again.
