As per the imgur link attached, the Laurel despawn speed is tied to framerate. At my usual fps of around 100 or so this results in a despawn speed of less than 10 seconds. This will and has resulted in a lot of cases of me seeing them despawn in front of me as I'm running over to them. I'm assuming this was just an accidental case of some spaghetti code, but just so everyone is aware you should probably cap at 60 fps if you want to have a decent chance at not missing possibly hundreds of Laurels regularly. (30 FPS of course is even better if you can stomach that)
