-M4 assault rifle was loaded with a double stanag magazine (60 rounds, takes 2 inventory spaces vertically)
-Only had 1 (1x1) space of inventory available
-Reloaded to a 10 round magazine (takes up 1 inventory space)
-The 60 round magazine was not placed in my inventory, it either disappeared or was dropped on the ground (I did not notice until it was too late and could not find it on the ground when i went back)
The 1 empty inventory space was not in the same bag/clothes piece as the 10 round magazine that replaced the 60 round stanag magazine
