So I made these bolts, see (this for more info)? They were pretty and round and looked like the real deal (just with the original textures). The problem with them was that the magazine they came in didn't have these bolts, so I went and fixed that.
Unfortunately, the mappers over at BMS didn't account for someone fixing their fuck-ups behind their backs, so their meticulously placed crossbow magazines will now look completely ruined (last screenshot). Learn from their mistake kids, never put your magazines in a way without leaving room for improvement.
