I rebuilt the structure from scratch to verify whether the same issue would occur, and I’m happy to report that I was able to place it correctly this time.
However, I was curious about what might be causing this issue, so I have shared the actual build to the Gallery.
・Reference for bug testing
This is the building where the bug was actually encountered.
・Bug testing results
This building was completely rebuilt from scratch.
If possible, I would greatly appreciate it if you could take a look at the differences between these two builds and share any insight into what might be happening on the game system side.
This may be slightly off topic, but I have previously encountered issues related to the instability of room states when building with curved walls.
It was possible to place straight walls overlapping the curved sections, and that area later caused an infinite loading issue.
In another case, when I removed all walls except the curved portion (from an indoor preset), then created walls inside the room (within the preset area) and deleted them again, the curved wall disappeared. Even after undoing the action, the curved wall did not return.
After experiencing several cases that suggest the instability of indoor/room recognition,
I have had to rebuild from scratch multiple times. I would greatly appreciate any advice you could provide.
