I had just unlocked the Steppenwolf faction. when you join a faction you will receive the level 1 parts. I didn't receive these parts (2x APC roof part, 2x Thin strike plate, and 2x the slope part). I am not sure why I didn't receive these parts. inventory space remaining doesn't matter but still, I'm not full. I don't understand where they are. I have bought a pack (the spider one). I believe its glitched.
