I'm pretty new to this but I do understand the basics. Just to practice with the geck I'm creating my own player home. It was going well bUT when I started the gec and loads my esm'S all my walls, and floors were gone. Everything else I put in such as door, bed, lockers, and everything else is there, but the walls are all gone. This is not the first time it has done this but I keep trying hoping it's my own mistake. Any ideas?

Here are two quick questions to kick things off:

1) Are you designating your mod's .esm as the Active File when you open the GECK?

2) Are you selecting the same .esms every time for your data when you open the GECK?
