Try removing that ceiling lamp on your pic.
Maybe the other houses have similar issues ?
It does sound like it might be related more to the builds than the Sims. The ceiling lamp was my first thought as well.
Unless there was a lot that one sim could cook and another couldn't with no build changes? If that's the case, it might actually be the other household members getting in the way. I've had cooking route fail before because another sim in the household was coming to grab something out of the fridge and even though they weren't there yet the fridge was "locked" to everyone else. Or because another sim or pet was just standing in front of the fridge or stove and wouldn't move.
Tested it today - looks like it is in fact the ceiling light👎. Which is slightly annoying since it's an allowable placement with move objects off. I can't remember if the light was in the same/similar spot in the last house, but that prev setup had worked for a good while before getting the movement error. For now I shall try a different light or placement and hopefully that lasts. Thank you both!!
