So I started a new game under the latest version using lowest graphics settings so as to not tax the GPU (although it's a 3060), all goes well until I decided to add a new manor up the hill - I placed a bailiff's office, a watchtower (because the bailiff needs fortification) and then some splendor parts behind it, including some fencing parts to create an enclosure.
once I finalized the build by clicking on the "build all" button - the game crashed with the long wait for the message,
as usual, I've attached the log file, latest save (5 minutes before, so I'm not sure it will have the new manor) and a picture of the fencing I was building behind the structure so you understand what I mean (the log might indicate the fences were placed too close to each other - if so, there should be a warning, I think)
