Same with ammo bags. I made another thread on it not long ago but it is now dead. It must be across more than just 1 platforms since you are PS4 and I am PS3. I am moving to PS4 in the next couple of weeks as soon as they come in stock though, so I already know to look out for this issue.
Same hare happens a lot since the servers are rubberbanding and laggin allover the place
in my experience it has only been happenening if i have my pistol out… try it with your primary and then try it with your pistol and see if that effects your outcome…
