I had a confusing sequence just now, ending act 1.
I cleaned up Creche Y'lek and went to Lady Esther to sell the loot, but she didn't have enough cash. So I sold as much as possible and then fast-travelled to the myconid colony to sell the rest to Blurg.
But I ended up in camp instead of the Myconids. When I wanted to leave camp to continue to Blurg, I got the message "You can't fast travel right now".
I didn't find any reason for this in the campsite, so the only thing left to do was to take a long rest (even if I didn't want to at that time) and hope that I could travel again afterwards.
That was when Voss's scene triggered. After going through this, I still couldn't fast travel. I tried long rest again and then we slept the night and woke up.
At none of the 2 long rest choices did I need to select food.
After waking up, I "left camp" expecting to return to Lady Esther, but I ended up in the Myconid colony.
