I've seen that this is a very, very, verrrry old bug that apparently still exists. Has there ever been a fix? I've just started playing, so I immediately noticed. So far the two I've picked up in world, the one on a mountain peak near main village, and the one after the first story raid in the hut. Seems silly to even consider DLC if such a basic issue exists. Reading the old reports was funny though 
ubisoft: whaaaa? Are ya sure you picked it up, you and these other fifty thousand people are having identical issues but we need proof lmfao!
