"THE MAIN ATTRACTION" Achievement seems to be Bugged

[p]

I just played a game with 1 friend on Easy mode, skipping straight to the concert finale of Dark Carnival in order to get this achievement. A couple of minutes into the event, 1 other friend joined us. We, obviously, remained on the stage for the entirety of the finale; however, when the helicopter began to arrive, the only person to get the achievement was my friend who joined late. We retried, a 3rd friend joining us just before we alerted the horde, but no one else got the achievement. Finally, the friend who got the achievement started the lobby and we all joined after the finale had started. Still, no dice.

To summarize, despite having fulfilled the qualifications for this achievement 3 times over, I still do not have it. 2 other friends of mine are experiencing this problem. Has anyone else had any issues with this achievement? Any possible solutions? I have heard that "BEAT THE RUSH" is bugged as well, so I suppose it wouldn't surprise me if this one were bugged as well.

Easiest way to get it is to just play the Last Man On Earth mutation (solo offline, obviously).

Can confirm. Didn't work in regular game, worked first time in Last Man on Earth.

Alas, I just got the achievement via Last Man on Earth — no issues. Not sure why this doesn't work normally. Thanks!

Did it online with someone, didn't get it even though we never left the scene.
Played it again singleplayer (no mutation), got it first try. It's def bugged but still possible to get.

Can also confirm, You can skip to the finale and do it easily with the last man on earth mutation.

I got it first try with bots in singleplayer campaign. From reading the replies, maybe it’s only bugged in multiplayer?

Do it in local server. That should do it.

Yes it's bugged. It registered on the 4th try for me.
