After the most recent patch I tried to use a tranquilizer dart with the crossbow just like I always have but the game wouldn't let me load them. I made sure they were in my inventory, and had the crossbow equipped, but the ammo showed red "0" with no mags listed, and pressing R to reload them wasn't working, even though I had 2 in my inventory. The 2 I had were ones I had picked up before the most recent patch. What gives?
