Some of my walls are being displayed invisible/transparent.
Unclear. Maybe the update corrupted certain rooms.
People that are affected by the issue say that downloading the affected house will bring the bug back. If you re-upload the affected house after fixing it, it’s fine.
Not all houses are affected by this and the same house can give one player troubles but not the other.
Try the following things. If one works, your can skip the rest.
- Re-apply the wall paper
- Re-draw the affected wall (all at the same time). The old ones do not need to be deleted.
- Delete the affected wall and rebuild it (one after the other)
