### Quoted from "C0llis"

The SUAV doesn't always kill on impact, but sometimes instead does <100 damage (often the targets are so far away that they don't die during the "assist window" but I once got a 68 assist). This seems to coincide with the target being crouched or prone although I haven't got any data besides anecdotes.

I'm up for some testing if anyone's interested.

I think that may have to do with it destroying itself on impact before the collision damage is totally given out. It's also possible to kill people and have it not self destruct if you pull up sharply after hitting them.

Hey guys.

Has anyone experienced a bug where, soon after spawning, bullets seem to do no damage to enemies. No hitmarkers or anything, I've experienced it a few times in the previous two days. Once on Zavod with a Carbine and again on Pearl Market with a shotgun this time. It doesn't feel like lag, as I move, as well as see enemies moving, perfectly well.

yeah,had it happen twice in a row onlocker some time agoit's a known bug with unknown cause,it also doesn't happen really often so it's not given much credit.

Ah, ok. I guess it's fine, it was just hilarious to put five shotgun shells into a guy's back and have him bunnyhop away!

I've had that happen to me a couple times since DT. I'll check if I recorded the events, IIRC the events triggered after I had parachuted. When it happened my gun fired, I spent bullets and had normal recoil, but there was no sound and I did not score any hits.

Also: I've had the shotgun thing happen to me as well. It was during a round of lockers and I know I recorded that so I will upload that for sure. The round was plagued with weird occurrences where I was certain that I was on target but I didn't seem to do any, or very little, damage. At first I though it was my aim that was very bad that round but then there was one occurence where I spawned on C and somehow was placed in the middle of the enemy cluster pushing from B (didn't know there even was a spawn point there). I had a lot of backs turned to me and started to unload, point blanc, and I knew for sure my aim was on, but I didn't score any hits. Oddly, my Deagle was able to damage enemies. At the time I thought the server was just acting up, but now I think it might be something else.

I'm currently on my laptop, but I'll go over to my stationary soon, do some quick editing and upload.

### Quoted from "Watcher-45"

What kind of question is that? Since when is cheese ever a bad idea?

### Quoted from "LeGarcon"

Hardline is a fun and sometimes silly Cops and Robbers sorta thing and I think that's great. Or it would be if it didn't suck.

I thought this was spawn protection. You know where an enemy materializes and as long as he doesn't move will not take damage. It was commonplace in BF3, but I can't remember if they removed or shortened that feature in BF4.
To Aim Assist or not to Aim Assist, that is the question.

...IIRC the events triggered after I had parachuted.

That's interesting. Thinking about it, this may have happened for mine, too. The one on Market, with the shotgun, I'm almost certain. Can't quite remember the others. It was certainly possible that I was parachuting, though. I'll be on the lookout from now on.

Also, does anyone ever get 19 rounds in a mag whn reloading the G18? It should be 20 or 21, right? I've had it happen several times, both on tactical and full reloads.

Ok, so I looked through my footage and found some weird instances of my shots doing no damage and producing no hitmarkers - even though the enemy models flinch. I have recorded a total of 4 occurrences, although I know it has happened at least one more time (Pearl Market, don't remember the gamemode, but I remember parachuting down from a roof and unloading into a guys chest only to do no damage). All the events I have recorded occurred shortly after spawning, so in light of that I think it is likely that is when the bug is triggered, as opposed to my earlier theory about parachutes (thinking back I think I may have spawned shortly before parachuting down during the Pearl Market incident). I previously thought the last two events (Op locker) was just the server acting up, but now I don't know.

I edited the events together, they can be seen here. The events were recorded between August 12 and 14; I don't remember when the event on Pearl Market happened. It's possible that this is two different bugs: during the first two videos the guns don't produce sounds while firing, but during the last two clips you can hear my gun firing. And just to clarify: all these events have been on the live version of BF4.

Edit 1: I just noticed the first two clips are from CTE. I didn't notice the watermarks earlier and for some reason Shadowplay saves CTE videos to the BF4 folder, despite it having generated a CTE folder. I'm not sure how interesting the first two events are now.

Edit 2: The thing in the first two clips just happened to me on a live server. I tested and it persisted through a reload, but disappeared once I switched weapons. I will upload it ASAP. I've uploaded it here . I've looked back at the raw footage and I died while shooting just before the first two events in Video 1 and before the event in Video 2.

I've had this happen a lot and so far only on the AR160. Notice how you don't have any gunshots. Firing animation plays but you aren't actually firing.

This is the heart of these "disappearing bullets."

Firing, but not actually firing.

19 in mag 1 in barrel, the stats list the "max ammo possible" (for some reason)
