Can't do that in this mode - error message

[Deklitch]

Hi,
So I've just been expanding my dynasty house by building upwards. I removed the roof, put up the walls, put in a spiral staircase, made little patios and put future generation skilling objects on said patios, and put up a new roof, still no problem. I go to send my gen 2 spouse up there to learn alchemy (so he can plant the original ingredients for the future alchemy immortal.

I then realise 'ooh, I forgot to put doors in up there'.

So I return to build mode and select the surplus sliding door. No problem, I go to where I want to put that door, and I get that error message. I am in building mode, and I am trying to place a door that I've placed many times before. The placement icon along the bottom of the door is green, there is nothing/no one in the way.

So I click the tick to close the error message, return to live mode and then return to build mode. I try to place the same door in the same place. This time its a success. I place the door in the other places I want it as well, also a success.

Any idea on why I'd get that error message? Any idea if it is the first step of something major?

I am not sure what's going on. I've never gotten a message like that. But I don't normally build/renovate a house while a family is living in it either. I build/renovate my houses in a different save than the ones I play in.

Would you be willing to share the house to see if I can recreate the error you are getting?

Of course, I'll do it after work tonight.

Thank you Mrs Flynn.

Sure!! If you'd like to troubleshoot, just for grins. You could take it into a new-test game without a household in it to see if it gives you that error or not.
