Well, at least I now know that Marco Polo works. No - I didn't lose the drone. I lost the tracker. I thought I had put it in the M2ED case, but couldn't for the life of me find it. Searched high and low for it in the room with all the drone paraphernalia. Couldn't find it. So I turned on the locator to see if it could find it. Bingo! Right off the bat it told me the tracker was very close and finally pointed to a knapsack (which I had already searched.) Searched the pack again. Nothing. So I removed everything from the knapsack and the locator STILL said it was in the knapsack. Searched the knapsack again and nothing was in it. I removed everything from the room except the pack and the locator still pointed to the knapsack. The locator kept beeping at 99% and was adamant the tracker was in the knapsack. Looked very, very carefully in the knapsack ... and lo and behold there was a hidden compartment where - sure enough - I had placed the tracker for safe keeping.
