BUG-ID: 6.1.6.1
Description:
There is no terminal to interact with in the middle of the platform room in basement of the Atmospheric mission. Nothing helps.
Location:
Mission 6 part 2
Consequences:
Unable to continue campaign
How to reproduce:
On the ground floor, when doing the infinite onslaught event. Instead of using the terminal to close the door and stop the event, just ignore it and run past everything and reach the elevator at the end. Elevator will not work since the event is ongoing. Head back and use the terminal to end the event. When you now reach the elevator it will not update the mission objective anymore.
I also posted a video of how I reproduced the bug in the forum thread.
Possible fix:
Reload earlier save from before doing the infinite onslaught event.
Workaround:
Just use the terminal as intended to stop the event, and not run past it further into the map.

8 - The Map-file Project
In some cases there are no solutions to a bug blocking progress.

But there is a way to get progress without losing your squad.
The way map-files work in your savegame folder is that mission objective progress is stored in each map-file. So if you replaced the map-file for the specific mission you are stuck on, with a map-file that does not have that problem, then you should be fine.
It does mean that in order for this to be useful, a library of many map-files of the same mission, each with a bit further progress saved would need to be made.
This is a lot of work.



Update:
I have now uploaded map-files to Nexusmods.
Project is completed.

Final Words
This is a work in progress.
Will try to update when new bugs are posted on the forums.



Happy Gaming!

I had a bug recently: I entered an elevator just as I was about to get a massive onslaught. The onslaught triggered after I selected the floor but before the door close. When I went to the new map, I had the onslaught timer but nothing came, and no Aliens spawned. The game got stuck in onslaught mode, and I couldn't get out of it. I couldn't extract either as the ARC doesn't let you do it while in onslaught. I had to reload an earlier save.
