As the title says. Only one cell in secondary, you need two to finish and get another bulkhead key to continue.
First the level has a broken overload cell, and now this...
#R4C3 Secondary - zone_266 no cell

It has been known. Unfortunately, only thing you can do, is go to the first terminal (on drop, it's on the right) and LIST CELL, if it has only 4, restart.
In theory I think you could grab an extra cell from Overload and use that, but it'd mean having to do ||Error alarm|| and then Secondary.

Can confirm, our group didn't get a cell in 266, locked up the level, can't continue and had to restart.

this is true. just not sure how long that window is and if it's enough time to use the list cell command. it's also an option to have the other 3 party members join after the mission is started and the terminal is checked

This still isn’t fixed. There’s basically no way to know this can happen before you experience it at least once. Still a waste of time, and boosters even if you know to check the correct number of cells. Would be great if it was fixed in a timely manner… But with the track record all cells may just disappear if we get an update within the next 2 months.
They have confirmed it’ll be fixed next patch: https://www.reddit.com/r/GTFO/comments/133wock/comment/jj7hyhw/

Devs say it will be fixed next patch. So clearly it can be fixed. They wouldn’t just go on the internet and tell lies.

Has this been fixed, but not brought up in the patch notes?
Because i still don't see it mentioned. Haven't played in over a month, and probably wont if this isn't fixed.
