This bug causes characters to become completely unresponsive to user input and run in a straight line for a short interval after attempting to pick up an item while running. It happens in both PvP and PvE and can be extremely frustrating. Since character control is such a fundamental in any game, I find it surprising that this has not been addressed. Perhaps an ANet employee could comment, as I am sure the vast majority of players have experienced this bug at some point, and it has been in the game since release.
