I painted a 75rd ak mag that was on the ground, and when it didnt appear, I assumed it was glitched because I didnt have space in my invintory, and my hands were full. So I made space for it, and relogged. When I spawned in, I had an akm with no attatchments, and the 75rd mag was on the ground where I painted it.

Worth noting: This happened once before when I relogged to fix a glitched invintory space that would not let me place items in it. Exact same description.
