Okay so i was loading quite a few caches on my 400t and after doing so I realized that half of them didnt show up on my GPS. yet when i go to reload the cache, it says the "file already exist, okay to reload?". Anyone else see this? for example, i loaded a set of 3 caches: Tango Base One, Two ,and Three. Even overwrote them, yet when i go back to view them on my GPS, it doesnt list them. I can even search by GC code and get a "not found". i probably loaded 200 caches and about 100 +/- made it on the unit. still love it tho.
