I just encountered this problem with an older build, built prior to terrain tools - somebody informed me it was now placing backwards and when I placed it to check it, sure enough it placed backwards on every lot I tried it on. When trying to rotate the lot I got the same message as the original poster. This is not a cc or mod problem because I have neither in my game and it is not limited to an elevated lots as this was an older lot before the tt patch.
The same issue in my game. Probably Maxis creators overlooked this problem It qualifies as a bug.
This is not a case of old CC / mods. 🙂
I checked in my game and I agree with @ schnuck01 and @ kreatora.
This error occurs only in the case of old houses that were built before the November update.
When turning the house on a plot, the ground (grass, land, etc ...) formed under this plot does not rotate. And that's why this error arises.
