Sometimes random chance has a mind of it's own. This morning I did the Fallen Cranes Construction Site CP to try and get a D50 pistol to craft an Exotic Liberty Pistol. I have collected all the parts and the blueprint just need the D50 and since pistols are targeted loot with increased drop chances in that area I gave it a go. Did the first part and then onto the defend part, yipee got a D50 pistol to drop from one of the hostiles I killed. Took over the CP and headed to the supply room to see if I could collect anything of interest, opened the cache and guess what was in it, a Liberty Pistol, go figure.
