When I used the hide object module in the editor to hide a building on Altis and placed a building from Livonia in its place, the AI would often walk through the walls or would not attempt to garrison the newly placed building if commanded to move inside the building. Worth noting, the walls they were walking through were the locations of the previous building's entrances. However, if I moved the Livonian building a few meters back, away from the hide objects module, the AI had no trouble moving inside. I'm using Version 1.98, with all DLCs and no mods enabled. This has also been replicated using building from Global Mobilization as a replacement as well.
