I have encountered a strange bug. In my current town, I started constructing roads. While my hearthlings were building that road I began to design a wall around my town. That wall was built directly next to the road in one area. As soon as the design touched the road being built my building name changed from Building No. 50-something into building No. 20 (Which was the road) and the road voxels the hearthings had placed already disappeared. Now that road and the wall I was designing became one building. I decided to make it anyway and instant-build the wall/road combo.
Not thinking much of it I continued with my town and eventually started to design a tower on the upper tier right next to where that wall connects. Anything I design up there, if it touches that wall, becomes building 20 and part of this mega-structure.
I was going to build a tower next to the wall right next to that blue-roofed entrance.
One last thing to add: The wall/road was build using instant build console command, so its completed. However if I click on the building it opens the building editor and I can apparently pause construction/start construction. Pressing the button doesn’t do anything, the hearthlings still do their other tasks
