Halo 4 Composer mission: Can't leave room with 2 hunters

Apparently the door with a red light is supposed to turn to a green light, but it isn't. Restarting checkpoint doesn't fix it either.

Is that the room where you have to pick up the grenade launcher thingy? It’s been ages since I played 4, lol. (I played it on legendary coop on my 360 when it came out, never played the campaign a second time. I’m working my way through the story again on pc now.)
If that’s the room I’m thinking of I think you need to grab that weapon and kill the hunters before moving on iirc.

We killed the hunters, all the scientists then surround and point their gun at a door that's supposed to have the button turn green but it doesn't. We ended up loading from the 2nd checkpoint in the mission to get passed it, but since we had to do it we didn't get the achievement for clearing the mission.

Jesus christ, they still haven't fixed this? wtf

In the closing days of this year of our lord 2023, they have still not fixed this softlock.

Bug is still here in 2024, coop legendary. We restarted 3-4 times and we killed the Hunters on different orders (we were doing left > right everytime, we switched to right > left idk if it changed something but it worked) and we didn't walk close to the door before the scientists. GL

Ran into this bug and this was the only result on Google referencing it.. restarting to last checkpoint didn't work, we had to restart the entire level.

I noticed that Cortana's line the first time the station gets scanned didn't play the first time, where the hunter room bugged, but did play when we restarted the level, and then got through the hunter room. So if Cortana doesn't say something about Diadact not knowing where the Composer is, you might run into the bug. Nothing to do with how you fight the hunters, seems to be an issue where a checkpoint gets missed entirely earlier in the level.
