I clearly shot him multiple times and it gave out a puff of smoke at least once as if I shot a wall. The first shot was also a clear headshot (He was sitting completely still right infront of me). I've also had this happen while using the dmr, idk why the bug occurs but you can sometimes shoot someone and the shot will clearly hit but do nothing, sometimes but not always creating a puff of smoke as if your shooting a wall. This bug is very annoying and has gotten me killed multiple times. Idk how to but if I could submit a video I would and you would see the bs occur.
