Immediately after the ramp leading up to the room with the Rally point before Dredgen Seer, if you go up to the top without going through the door, the door will close in front of you and lock you out of the rally point room (and beyond). You are left with about 2 feet of space between the door and the rest of the level, which is now declared out of bounds since the door shut. Instead of a "Joining Allies" type of OOB, though, you get "Turn Back!". Which as we all know, will kill you in 5 seconds. I just lost a solo flawless run because I opened my menu on the threshold and when I was done adjusting my loadout, I was greeted with a closed door and this current predicament of needing to return to orbit or die to proceed. This needs to be fixed urgently. Its absurd that this is coded to be "Turn Back!" instead of "Joining Allies".
