I don't know if anyone else has noticed, but the Empty Sunset Sarsaparilla bottles in Zion Canyon can't be used to make Sunset Sass at the campfire, and don't stack with Mojave Wasteland bottles. I'm guessing it's because they have a different form ID. If the devs are working on a patch to fix ED-E, maybe they could slip this in too, eh?

heh, kinda like how you can't get paid to recycle bottles in Utah, but you get five cents each in Oregon~

Kind of like how cactus water is impossible to make in the main game, since 'Empty Soda Bottles' don't exist. All my Empty Nuka-Cola Bottles, useless.

Oh there are soda bottles. They're uncommon. Old Lady Gibson has some, and I know there are a few around elsewhere.

There's a truck with 3 crates of them at the bottom of the hill leading up to Mojave Outpost, and almost every building interior has some lying around.

I do sometimes wonder why they did not make it so that drinking a Nuka-Cola gives you an empty soda bottle...
