Weapon bonus changes randomly

[Ac1dBurn]

My weapon bonus (acquired by fully leveling a gun) keeps randomly changing.
One moment it's +5% crit damage when crouched then it's 6% bonus damage from behind then x1.03 damage increase, ....
This occurs mostly after doing an coop mission.

Not sure if it happens with all weapons but it seems to happen always with the EMC assault rifle and EMC sniper rifle bought from the vendor next to the Mayhem: minigun rampage.
It might be worth nothing that I have multiple such weapons in my inventory since I swap them out to level the weapon skills.

My assault rifle dose this too, first it was +15% damage to vehicles, then it was +5 mag and now it is +4% ego power duration on crit kill.

It sounds like a coding error with the weapon itself and the server. Every time your client tells the server to load the gun (IE. during a loading screen while going into/out of an instance) the initial stat for the gun isn't saved, so it keeps randomizing that variable.

Yea, same thing here. I actually like this idea, it keeps your weapon fresh with new and different boosts. Its an added bonus anyways so it is not like your core boosts are changing.

I think it may be either time based or like you said after certain missions. I bet it has to do with the amount of kills you get and then it switches...Just a thought.

I don't think this is working as intended since not all weapons do this.
I believe it is a bug and while I understand your view I disagree, different bonuses accommodate different play styles, like melee damage increase is more connected to blur while increase in crouched crit damage is connected to cloak.
