Fallout NV DLC: Old World Blues Bug???

[lion.on.tour]

Hello!
Currently playing "Old World Blues" for Fallout: New Vegas.
I am now at the point where I have to get my brain out of the box in the laboratory of Dr. Möbius.
If I speak to my brain, one comes to the place where the brain talks about the things it has already experienced with us.
But from this point onwards, it tells only two stories (liberation from HELIOS One and another). From now on, only two alternate windows appear. These can not be pushed, not jumped out, or otherwise terminated. - I press the first window away, comes the second, I push the away comes back the first etc.

At first I thought that this is perhaps the intention (I would certainly believe the Fallout series), but also "back and forth" after just one minute, I can not get out of this "text window loop".
Please help me...........
Lion

The helios one part is a glitch in everyones games, load the autosave you got when entering moboius's room and talk with your brain again without taking that dialogue option

There's a bug where these lines loop forever "HELIOS One coming back on-line." "Jason Bright and his followers launching into the vast unknown."

This console command will make the game think you haven't powered up Helios One and should avoid having your brain say the bugged line.

Then once your brain moves on to the next line you can set it back to how it was before.
