Q: Help, the carpet/floor pieces sink into the floor below causing flickering!
A: Place the guide piece down first. Then attach carpet/floor pieces to the guide piece. Finally scrap the guide piece and replace it with a carpet/floor piece. Attempts to place the carpet/floor pieces directly will not work properly.
Q. Help, the NPC's won't walk on the carpet/floor pieces!
A: This means that the floor beneath the carpet/floor pieces itself is not navmeshed. The pieces in this mod cannot be navmeshed themselves as they are so thin it would conflict with underlying navmesh. Use a navmeshed foundation to place these pieces on.
