That does sound like a major bug Misermelo, worthy of not playing the game 6 months for so they might fix that!

The amount of frustration this single development has caused is leading gamers away from D:OS. Think about it. You play for hours until you realize you've completely wasted your time and efforts by not being able to get anything remotely decent despite carefully developing a strategy and characters.
Exaggerating much?
Bethesda games are way worse than this (all of them) even after the final patch, and apparently they do just *fine*... as apparently does D:OS. Since it's really not that bad as people want to make out...
Lastly;
Campfire + Cooking pot is supposed to place the Mobile Kitchen on that spot (it's not supposed to be carried around). Although it does seem there are quite a few broken campfires around who do not properly spawn the mobile kitchen and dump it in your inventory instead.
