B42 is native to M1 Macbooks, it would not be recommended to use Parallels for it as we would not be able to support issues with Virtualization like that. I would suggest running it natively if possible to see if you still run into issues.
I destroyed one of the walls on the staircase and walked above the ceiling of the bunker, turns out, the undergound isn't filled with anything, its just an empty void where basements are the only constructions and hitboxes.
On another note, generators power things 2 levels up and 2 levels down, so:
POWER
POWER
GENERATOR
POWER
POWER
Fumes only go upwards, and they do disipate. It takes a day or two. So
FUMES / NO POWER
FUMES / POWER
FUMES / POWER
GENERATOR
POWER
POWER

Think of it as hot gases going upwards untill reaching open air
I haven't tried with a Sweet Pie yet, but I've made a couple Savory Pies and it's happened every time. The recipe says when you cut the pie, you need a knife (which you keep) and a pie (which you lose). And you get 5 slices of pie and a pie pan. In every case, I've used the knife and I've gotten a pie pan and 5 slices of pie, but the original pie isn't getting deleted. It's possible that the "Hunger" value is being decreased, but it would allow me to cut this pie something like 50 times, resulting in around 250 slices and 50 pie pans, all from a single pie. Which seems like a bug to me.
Also, I noticed that the slices of pie no longer include the Seasonings you used. For instance, I just created a savory pie made from 3xFresh Broccoli, seasoned with pepper, onion powder and garlic powder. The resulting slices of pie only say they are made with the 3x Fresh Broccoli. There is no mention of the seasonings that went into the original pie.
