Incidentally, if you're cooking with low-skill chefs, you'll almost always get food poisoning. I'm going through a bout of that myself.
The solution: Set only one person to cook, hopefully someone who has a learning boost for it. That way you get a high-skill cook in a shorter amount of time.
I did only have one guy who could cook, but he only had a skill of six. I did notice when he hit 7, food poisoning among the colonists seemed to dwindle away.
Of course, the chickens are still gorging themselves on rice, corn and potatoes and throwing up constantly.
I've got other frustrations now.
It's my third (or is it fourth?) winter and I've finished researching EVERYTHING, though I don't have what I need to build a ship yet. The map I'm on this time seems to be particularly "compacted machinery" poor, so I'm having to construct my own "components" out of raw steel, which takes FUH-REH-VURRRR. Especially given that I only have one colonist (out of ten. TEN!) who is skilled enough to do the work, and he's also the only one skilled enough to do things like make clothes. His crafting skill is like 16 now, it's unbelievable.
Anyway, this hasn't stopped "Phoebe Chillax" from deciding it's time for us to die. We've gotten yet another round of toxic fallout PLUS a cold snap this winter, and I'd already had to revert to a previous autosave when fate conspired to screw me. (Since playing Undertale, I've felt more of an... obligation to savescum away disaster... anyone who's played it will understand why).
Anyway, last night's final frustration was a Poison Ship crashed in front of my compound, just out of range of my turrets, and all plant life around it started dying off almost immediately, in an ever growing ring. I at least had the foresight to first build a line of sandbags for my guys to hide behind to shoot at it, but even that isn't enough.
I saved right before ordering them to open fire. Seven colonists, mostly with rifles and SMGs but I do have one charge blaster, so I was not expecting disaster, buuuut... it happened. Open fire on the ship, THREE CATERPILLARS and FOUR SCYTHERS pop out, all using charge weapons/rocket launchers/miniguns. They cut down my colonists like grass. I reload the save, try again, and the configuration changes every reload, but it's usually 7 automatons (automata?) of mixed flavor, all carrying enough ordinance to mow down the army of a small nation.
I must have tried twenty times for a different outcome, but every attempt ended in complete defeat. I am probably going to have to load an earlier save, from before the poison ship event, and hope Phoebe decides to do something different. I feel dirty.
