This is driving me crazy, its happening ever since the 1.8 firmware update. When I fly I normally cache my flying area over wifi at home before I go out. Never had an issue in the past, I cache my maps, go out to fly and the area is there. Since 1.8 I do the same thing, cache my maps, go fly and everything is there..........until I go out and fly again. I can go back to the same area and get nothing. Its like the area I cached has been erased. I've checked all my settings and everything is looks good. What the heck am I doing wrong? I never had this issue in the past
