I have the anti material rifle. when i use incendiary rounds and try to use vats, then just exit out without selecting a target they catch on fire. It doesnt matter who or how many, if i vats them they catch on fire. I dont get in trouble no matter who i kill and i dont get XP for it either. It happened the first two times i played too. It also does it on my husbands profile. Is that just the way its supposed to be or is it a glitch??
Its a glitch. Pretty sure it has been fixed in one of the patches. How it works is the effect is added when you aim at someone in vats rather than when the gun is fired...resulting in a glitched way to kill anyone you want...even the final boss.
