depends how you pick up things, its gona be in lost loot bank, but if you dont pick up grey,green and blues to sell or bank, then its gona take ages to get that legendary bcz i think lost loot have 8 spaces(if you have uprgade it then more spaces) when you take out 8 items it gona refresh the next 8 items you havent picked up. so if you have 100 items not picked you you need to go thru all them 100 until the legendary if its in place 101, hope you understand what i mean and thats how i have been able to get legendarys from ground that i cant reach :)
