So I just did the quest with Hosea and the legendary bear (first legendary hunting quest), I got the skin but I met the woman stuck under her friend's horse. I had to throw the legendary skin for her to get on my horse for a trip to Annesburg. I was thinking "I will be fast enough for the skin to stay here".. But when I got back at the exact same spot, the skin wasn't anymore..

My question is : Does legendary items like this can disappear ? What can I do to get it back ? Is there a NPC that stole my skin ?
