Can't get the achiev "Not invited"

[Nero5th]

I killed, in 5 seconds, 14 cops and more in Watchdogs but can't get the achiev dunno why. The proof, at the end it says that I get 14 ennemies with the grenade launcher (without incendiary). Someone who doesn't have it can test because I tried like 6 times but still nothing.

I tried it yesterday and i have the same problem :/

I don't suggest abusing bugs, but since this sounds like a bug, try this.

1) Start offline heist (maybe Watchdogs)
2) When the doors open, kill your first group and count to 10
3) During this count, kill as many as you can
4) When you count 9 (or 8 to be safe), hit the restart
5) You should have all the time you need to get your 10 enemies after your restart due to some bug. In this case, keep killing with the Piglet until you get your achievement.

Tried many times today, was unable to get the achievement. Also tried what #2 suggested, but it didn't work for me, maybe someone else has better luck with it.

A lot of my friends have the same issue, so it's due to the update they made.

I tried for over 1h on Watchdogs Normal, Hard, Very Hard and Overkill. Nothing seemed to work! The achievement must be broken with the new update, I did unlock Motherforker achievement tonight though.

I did mine on rats, my crew would let them warm from the road and at the choke point between the cars and the road I'd just empty the pig there...instant achieve.

I just very recently unlocked this achievement myself.

Watchdogs on either Hard or Very Hard difficulty, no incendiary rounds
The truck door opened, and I started lobbing grenades. Achievement earned on Jul 9 (prior to our most recent update)

I know my info was pre-update, but I thought I'd share just in case it helps in any way.
It was working a week and a half ago on Watchdogs, and I got it in one attempt.. So it sounds quite plausible that the update may have bugged the achievement somehow.

[Nero5th]

I'll try it right now and let's see if it still broken.

[Nero5th]

Always the same. And it's not like this one only. There is a lot achiev which you can't get them anymore.

Do you use any game mods?
Some of them disable the ability to gain achievements because they make the game easier.
And some mods simply have adverse affects on the base game (such as messing up the ability to trip certain flags in the code / the ability to earn certain achievements), in sometimes unpredictable ways.

(Either way, I'd suggest you try 'Verify your game cache' and see if that helps. If you use mods, remove those before verifying game cache)

[Nero5th]

I don't use mods, only hoxhud and when I was trying to get this achiev, hoxhud was disabled because the devs were working on a new patch.

[Retroh]

Same problem, impossible to get the achievement. (´o_O`)

Did you got it, Seiba?

[Nero5th]

Nope, not even my friends. This is happened after the update Gage Ninja Pack.

I have the same problem, is there anyway to contact OK directly about it. Not that they will give a ♥♥♥♥ or try to do something about it if u ask me, but trying never hurts

[Nero5th]

I'll already send them an email waiting for answer.
